Question

A swimmer sprints a short distance for a competition. The swimmer is not able to take in enough oxygen to make the ATP needed for the sprint. Which of the following processes in most likely going to occur in the swimmers muscle cells during the competition? (2 points)

A. Aerobic respiration would continue until oxygen is no longer available, leading to cell death.
B. Aerobic respiration will continue to make the same amount of ATP since oxygen is not required.
C.Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen.
D. Anaerobic respiration will produce more ATP than the process used in the presence of oxygen.

Answer 1

it is c bc it says the amount of ATP needed. so, since the amount needed is not there, it will make as much as it can in its absence.

Answer 2

When the swimmer is unable to take in enough oxygen for the sprint, the ATP (Adenosine triphosphate) will be compromised. In such conditions, the body will use anaerobic respiration to produce the ATP. Anaerobic respiration takes place in the absence of oxygen. It used the electron acceptors in place of the oxygen in the respiratory cycle. The amount of the ATP produced is, however, less in anaerobic respiration.

Hence, the answer is 'Option C - Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen'.
