In glycolysis, the conversion from pyruvate to acetyl CoA is irreversible, but I found that during the synthesis of FA, acetyl CoA can be synthesized to citrate -> OAA -> Malate ->pyruvate when Citric acid shuttle, why we cannot say that pyruvate can turn back to acetyl CoA?

State if each of the following processes release or required ATP: (ATP PRODUCED OR CONSUMED)

a. citric acid cycle

b. glucose forms two pyruvate

c. pyruvate forms acetyl CoA

d. glucose forms glucose-6-phosphate

f. First six reactions of glycolysis

What is the ATP yield from one molecule of glucose and how ATP is generated at each process:

a. Glycolysis

b. Kreb's cycle

c. Electron Transport chain

Please specify if any ATP are removed from the total yield as a result of these ATP being required to initialise the reaction

Under which circumstances would a muscle cell be undergoing -oxidation instead of glycolysis? Select all correct answers.

a. Cellular ATP levels are low

b. O2 is limited

c. O2 is abundant

d. Cellular ATP levels are high

e. Blood glucose levels are low

Electrons bound by NADH from glycolysis, the CAC, and the Pyruvate Dehydrogenase Complex are transferred to the Electron Transport Complex (Complex 1, Complex 2, Complex 3 and Complex 4) a series of 4 protein complexes. What is the order the electrons will travel from protein complex to protein complex?
