Question

After Frida stops exercising, she continues to breathe heavily. What is most likely occurring in her body?

A. Heavy breathing during exercise has produced an oxygen surplus in her muscles. This oxygen is being transported to her lungs. This is a result of aerobic respiration.

B. Heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. Lactate is being transported to her liver. This is a result of aerobic respiration.

C.Strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

D. Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

Answer 1

Out of the choices given, what is most likely occurring in her body is the strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration. The correct answer is D. 

Answer 2

The correct answer is option D. Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

During exercise, the muscles use the oxygen present there and become deprived of oxygen. Due to less oxygen, the anaerobic respiration occur in the muscles, to overcome this, the heavy breathing takes place. heavy breathing brings the oxygen to the muscles.

During anaerobic respiration, the glucose is broken down into the lactate and the lactate is transferred to the liver for the gluconeogenesis and to maintain the constant supply of the glucose to the muscles.
