Question

In the Krebs cycle, what molecule acquires most of the energy that is released by the oxidation of acetyl CoA and how many of these molecules are produced durring each turn of the cycle?

Answer 1

The molecule that acquires the energy that is released is ATP. For every acetyl CoA oxidized 1 ATP molecule is produced. Usually 2 acetyl CoA molecules are oxidized in the Krebs cycle, therefore 2 ATP molecules are produced. The cycle also produces 6 molecules of NADH that are equivalent to 18 ATP molecules and 2 FADH molecules that are equivalent to 4 ATP molecules. In total there's 24 ATP molecule produced.

Answer 2

The end product of Krebs(citric acid) cycle is 2ATP and NAD and FAD. The NAD and FAD help to collect electron and hydrogen atoms that will be used in the electron transport chain.
