Which of the following is not a prerequisite for continuous aerobic production of atp?
a. acetyl coa must be present
b nad and fad must be available
c. oxygen must be present in the tissues
d. cellular enzymes must be present in sufficient concentration
e. all the above are necessary

E

Explanation:

Aerobic respiration mainly occurs in the mitochondria of the cell and is known as the Krebs/Citric acid cycle. It begins when pyruvate from anaerobic respiration in the cytoplasm which is converted to acetyl-CoA before entering the Krebs cycle. Acetyl-CoA is transformed and the energy in its bond used to enable oxidation of NADH and FADH2. The H+ ions are pumped to the mitochondrial intermembrane space. The generated proton motive force is then used to generate ATPs by ATP synthase enzyme. Oxygen becomes the ultimate proton acceptor which is reduced to water. This whole process is facilitated by enzymes in the cell such as dehydrogenases.

the answer is

c. parental
