|
|
None of the above

Explanation:
Detailed explanation-1: -The human body uses three types of molecules to yield the necessary energy to drive ATP synthesis: fats, proteins, and carbohydrates. Mitochondria are the main site for ATP synthesis in mammals, although some ATP is also synthesized in the cytoplasm.
Detailed explanation-2: -In eucaryotes these reactions all take place in mitochondria, the organelle to which pyruvate and fatty acids are directed for acetyl CoA production (Figure 2-78). We should therefore not be surprised to discover that the mitochondrion is the place where most of the ATP is produced in animal cells.
