Question 1

Fermentation is wasteful of the energy in food molecules and poses the threat of killing the fermenting organism in higher levels of toxic alcohol.Which of the following is not a reason why an organism would utilize fermentation?

Accepted Answer

Fermentation is not preferred but is utilized only when oxygen is unavailable.

Question 2

What is the input requirements of glycolysis?

Accepted Answer

The inputs of glycolysis are 2 ATP, 2 NAD⁺, glucose, and 4 ADP. 2 pyruvates, 2 NADH, and 2 ADP are the outputs of glycolysis. 2 ATP, 2 NAD⁺, glucose, and 2 ADP are the inputs of glycolysis.

Question 3

List the inputs and outputs of glycolysis.

Accepted Answer

The answer of List the inputs and outputs of glycolysis....

Question 4

Fermentation is the process that allows bread to rise.

Accepted Answer

Fermentation produces alcohol and carbon dioxide. The carbon dioxide produces bubbles that cause bread to rise.

Question 5

What are the correct outputs,during the citric acid cycle from one molecule of glucose?

Accepted Answer

The correct outputs, during the citric acid cycle from one molecule of glucose is 6 NADH, 4 CO₂, 2 ATP, 2 FADH₂. The glucose will split into 2 pyruvates, each of which will be converted into acetyl CoA which then will go through the citric acid cycle. 2 acetyl - CoA & 2 CO₂ are the end products of the preparatory reaction. 2 pyruvates, 2 NADH, 2 ADH, and 4 ATP are the end products of glycolysis.

Question 6

What is the most likely reason that cellular respiration would shift from an aerobic state into an anaerobic state?

Accepted Answer

All of the choices are reasons that an individual could shift into an anaerobic state. Any reason that decreases the amount of available oxygen can cause a shift into anaerobic respiration.

Question 7

Write out the overall equation for cellular respiration.

Accepted Answer

The answer of Write out the overall equation for cellular...

Question 8

The only end product of alcoholic fermentation is the alcohol.

Accepted Answer

Carbon dioxide is produced along with the alcohol.

Question 9

List,in order,the stages of aerobic cellular respiration and indicate where they occur in the cell.

Accepted Answer

The answer of List,in order,the stages of aerobic cellular respiration...

Question 10

Which of the following is not a consequence of the lactate that results from fermentation in the muscles?

Accepted Answer

Lactate causes that muscle "burn" and is not stored in muscle cells.

Question 11

Which of the following is not an example of fermentation used by organisms to produce ATP?

Accepted Answer

Humans do not produce alcohol from fermentation.

Question 12

Fermentation follows glycolysis in some cells if oxygen is not available.

Accepted Answer

Glycolysis converts glucose to pyruvate. Pyruvate can either be fermented if oxygen is not available or enter the preparatory reaction if oxygen is available.
