Answer:

A

Explanation:

The pulmonary artery carries de-oxygenated blood from the right ventricle of the heart to the lungs. It is the only artery that carries de-oxygenated blood. This blood is usually from the tissues and has a lot of carbon dioxide from the cellular respiration of cells around the body. The blood is pumped to the lungs to be oxygenated and the carbon dioxide expelled.

When not enough oxygen is available to cells during rigorous exercise, muscle cells must convert pyruvate to __________ to gener
Kipish [7]

The correct answer is: A) lactic acid.

During the exercise, muscle cells use anaerobic respiration in order to make enough energy in the form of ATP. Anaerobic respiration doesn’t require oxygen, but glucose is broken down to produce energy. Glucose is broken down to pyruvate in the process called glycolysis. Next step is convert of pyruvate into lactic acid (or lactate).

During the exercise, the oxygen level in muscle cells decreases, which results in anaerobic respiration of the cells.
