Which statement about cellular respiration is true? it produces oxygen. it requires water. it is used by every living cell. it converts energy to food.

The right answer is It is used by every living cell.

There are two types of breathing in living organisms:

The breathing mode using oxygen as the oxidant is called aerobic.

During glycolysis, the Krebs cycle, beta-oxidation and other biomolecule degradation processes, reduced coenzymes (including NADH) are produced. The electrons of these coenzymes pass on a chain of carriers. In the case of aerobic respiration, the final acceptor is oxygen.

Anaerobic respiration is a mechanism in which electrons pass through a chain of carriers whose final acceptor is a mineral other than oxygen.
