Why is fermentation considered an anaerobic process? anaerobic what are the products of fermentation in humans? what are the products of yeast fermentation?

Answers

Answer 1
Fermentation is considered anaerobic because it happens when no oxygen is present.
Humans--> lactic acid
Yeast--> ethanol
Answer 2
Final answer:

Fermentation is an anaerobic process as it does not require oxygen, with humans producing lactic acid and yeast producing ethanol and carbon dioxide. While yielding less ATP than aerobic respiration, it is vital for energy production when oxygen is scarce.

Explanation:

Fermentation is considered an anaerobic process because it does not require oxygen to produce ATP (adenosine triphosphate), the energy currency of the cell. Instead of oxygen, it uses an organic molecule to accept electrons during the breakdown of energy-rich molecules like glucose.

Humans undergo lactic acid fermentation, which produces lactic acid and ATP when oxygen levels are low, such as during intense exercise. This type of fermentation allows for short bursts of energy and helps to regenerate NAD+ needed for glycolysis to continue producing ATP.

Yeast, on the other hand, performs alcoholic fermentation, where pyruvate is converted into ethanol and carbon dioxide. This process is utilized in the production of alcoholic beverages and causes bread to rise during baking.

Comparison of Fermentation Types

Lactic acid fermentation: produces lactic acid, used by human muscles in anaerobic conditions.Alcoholic fermentation: produces ethanol and carbon dioxide, utilized by yeast in the making of alcohol and leavening of bread.

ATP Yield and Importance

The ATP yield from fermentation is much lower than aerobic respiration, providing just 2 ATP molecules per glucose molecule, while aerobic respiration can generate approximately 36-38 ATPs. However, the key advantage of fermentation is its ability to produce ATP in the absence of oxygen, ensuring that energy production can continue in anaerobic conditions.

During the initial phase of parachute training in soldiers, their testosterone levels _______ and their post-jump epinephrine levels _______.

Answers

The levels of testosterone, oddly, decrease. This runs counter to the idea that this would be a task that would be done by persons seeking a thrill. This may be due to the position that the soldiers hold: having excess testosterone in the body could lead to poor mechanics and performing the jump incorrectly. Also, post-jump epinephrine (or adrenaline) levels increase. This is due to the body needing this substance to stay alert during the jump.
Final answer:

During the initial phase of parachute training in soldiers, their testosterone levels increase and their post-jump epinephrine levels increase.

Explanation:

During the initial phase of parachute training in soldiers, their testosterone levels increase and their post-jump epinephrine levels increase.



Testosterone is a hormone that is responsible for male characteristics, such as muscle growth and aggression. During times of stress or physical activity, testosterone levels tend to increase to optimize the body's response. Epinephrine, also known as adrenaline, is released during fight or flight response and can increase heart rate and blood pressure. Therefore, it makes sense that both testosterone and epinephrine levels would increase during parachute training, as it is a physically demanding and potentially stressful activity.

If the calvin cycle slows down, what will happen to the rate of o2 production in ps ii, and why?

Answers

If the Calvin cycle slows down, THE RATE OF OXYGEN PRODUCTION IN PS II WILL BE REDUCED. 
This is because, the light reaction depends on the dark reaction to occur. If the Calvin cycle slows down, the light cycle will have less ADP and NADP+ to work with and this will slow down the production rate of the photosynthetic reaction.
Final answer:

When the Calvin Cycle slows down, the rate of O₂ production in photosystem II decreases. This occurs because less water is split into hydrogen and oxygen, leading to reduced photosynthesis. The outcome is lower levels of ATP and NADPH, essential for cellular biochemical reactions.

Explanation:

When the Calvin Cycle slows down in photosynthesis, it means that there is a decrease in the usage of the products of photosystem II (PS II), particularly ATP and NADPH. If these products are not used promptly, they accumulate, decreasing the stimulus for Light Reaction. As a result, the rate of photosynthesis, including the light-dependent reactions occurring in PS II, was also reduced.

In PS II, light energy is used to extract electrons from water, which results in the formation of oxygen gas (O₂). Hence, when the rate of photosynthesis decreases due to a slowdown of the Calvin Cycle, it causes a decrease in the rate of O₂ production because less water is being split into hydrogen and oxygen.

This situation can lead to a reduction in the amounts of cellular energy in the form of ATP and NADPH, which are vital for many biochemical reactions in the cell, including those in the Calvin Cycle. However, other regulatory mechanisms can alter this balance to adapt to the cell's energy needs.

A client with sepsis begins having labored breathing, confusion, and lethargy. what complication should the nurse assess for in this client

Answers

Final answer:

The client's symptoms suggest a potential development of septic shock, a life-threatening complication of sepsis. It can cause damage to critical organs and lead to organ failure, even death if not treated promptly. Bacterial infections are the most common pathogens leading to this condition.

Explanation:

The presentation of labored breathing, confusion, and lethargy in a patient with sepsis could indicate a severe complication known as septic shock. This is a life-threatening condition caused by an inflammatory response that becomes dysregulated due to the body's attempt to combat the infection. This overwhelming response can lead to damage to critical organs, such as the heart, lungs, liver, and kidneys.

Typically, patients showing signs of septic shock exhibit increased heart and respiratory rates, and confusion, and can rapidly deteriorate into a state of shock. They may experience complications such as disseminated intravascular coagulation (where small blood clots develop throughout the bloodstream), which can lead to organ failure and is often followed by fever, jaundice, and hypotension. If not treated promptly and effectively, septic shock can lead to renal or liver failure and potentially death.

Bacterial infections are the most common cause of sepsis and septic shock, with common sources including pneumonia, intra-abdominal infections, urinary tract infections, or infections related to indwelling catheters or wounds.

As global temperatures increase, sea levels rise. Which of the following is a way that rising sea levels negatively impact marine biodiversity?

A.) Fewer tropical storms and severe weather
B.) Less oxygen levels at various depths
C.) More light reaching plants and algae
D.) A decrease in the pH of the oceans

Answers

Answer:

Option A, Fewer tropical storms and severe weather

Explanation:

The water frozen in the glaciers is the purest form of water while ocean water consists of lot of salts and gases(such as carbon dioxide) which makes it acidic. Thus, when pure water of glaciers mixes with the acidic water of ocean , it dilutes the ocean water and hence  reduces its acidity. Thus, the pH of the water increases.

Therefore  option D is incorrect

Also the water level will increase and hence less light will reach to the plants and algae therefore option C is also incorrect.

Oxygen level will increase as the glacier water is the purest form of water and consist of dissolved oxygen.  Hence option B is also incorrect

Due to sudden melting of glacier there will be extreme weather and climatic conditions , hence option A is correct.

Answer:

The answer for this question is Answer choice B

Explanation:

This is due the rising sea levels causing less oxygen to be able to reach the lower depths. Plus I got it correct on my quiz.

How does a sunflower maintain homeostasis?

Answers

Final answer:

Sunflowers maintain homeostasis by using negative feedback mechanisms to regulate their inner environment. They adjust their physiological processes in response to environmental stimuli, like variations in temperature or water availability, and use the energy from photosynthesis to support growth and reproduction. The timing of flower maturity and sugar to fat conversions in seeds helps ensure survival.

Explanation:

Like all living organisms, sunflowers maintain homeostasis, the process of maintaining a stable internal environment despite changes in the external environment. Sunflowers use various strategies to regulate their internal conditions to ensure proper function and growth. One key example of a sunflower's ability to maintain homeostasis is their engagement in photosynthesis, using the C3 photosynthetic pathway. The sunflower is a photosynthetic autotroph that converts sunlight into the sugars needed for growth and reproduction.

The sunflower adjusts its mechanism based on internal and external stimuli through a process known as negative feedback. For instance, when there are fluctuations in certain environmental conditions, like water availability or temperature, the sunflower's physiological processes adapt to stabilize these conditions. Additionally, the sunflower's inflorescence also plays a role in this balancing act. The timing of flower maturity and the development of individual flowers work in a way that maximizes the chances for successful pollination and seed setting, which is crucial for the survival and reproduction of the species.

Finally, another aspect of a sunflower's homeostasis includes the control of matter and energy. Sugars produced via photosynthesis are transported as sucrose to developing seeds and used to create oils within the seeds. The energy for the conversion of sugars to fats is provided by the oxidation of sugars. Thus, through these complex feedback mechanisms, sunflowers regulate growth and reproduction while maintaining dynamic homeostasis.

Even though plants cells carry out photosynthesis, they still use their mitochondria for oxidation of pyruvate. under what conditions will plant cell mitochondria be active in this process?

Answers

In all cells, all the time

Even though plants carry out photosynthesis to produce energy and "food," their cells would still need to undergo cellular respiration, as with all other living cells. Cellular respiration occurs in the mitochondria of cells and produces ATP (energy) in the process. This ATP is then used by the plants in all its other processes. 
Final answer:

Plant cell mitochondria are active in the oxidation of pyruvate when the cell is performing cellular respiration, which typically happens at night or when light is unavailable. The process uses the glucose produced during photosynthesis to produce ATP, the plant's main energy currency.

Explanation:

Plant cell mitochondria are active in the oxidation of pyruvate under any condition in which the plant cell is performing cellular respiration. This typically happens during periods when light is unavailable, such as at night, and the energy stored in glucose is required. Photosynthesis, which converts light energy into chemical energy in the form of glucose, fuels the plant during the day. The cellular respiration process that involves the oxidation of pyruvate in the mitochondria then uses this glucose to produce ATP, the plant's main energy currency, when light is unavailable.
