List 3 macromolecular sources for acetyl CoA that can be used in the Krebs Cycle. Which of the macromolecular sources produces more ATP per molecule and briefly state why.
Homework Answers
The macromolecular sources of Acetyl CoA are carbohydrates ,proteins and fats.
Fats produces more ATP per molecule as compared to glucose and proteins.Because Fatty acids produces 3 Acetyl CoA molecules per 6 carbon atoms.But glucose produces only 2 Acetyl CoA molecules per 6 carbon atoms.so fat molecules yield more energy than carbohydrates.So they are important source of energy.

In reaction 1 of the Krebs cycle, acetyl-CoA formed in the pyruvate dehydrogenase reaction condenses with the four-carbon compound to form with the elimination of coenzyme A. Since the product has three carboxyl groups, this pathway is referred to as the cycle. In reaction 2 of the Krebs cycle, this product then undergoes to form The enzyme is called aconitase because the compound cis-aconitate is a(n) of the reaction. Reaction 3 eliminates CO_2 to...
