Homework SourseEach of the following statements about the citric acid cycle
Each of the following statements about the citric acid cycle is true except
| Acetate enters the citric acid cycle and joins a four-carbon acceptor molecule to form citrate. |
| The cycle involves the ordered activity of eight enzymes. |
| Substrate-level phosphorylation generates ATP/GTP at one step. |
| Oxidation by transfer of electrons to coenzymes occurs at two steps. |
| Decarboxylation to release CO2 occurs at two steps. |
Solution
ANS :Oxidation by transfer of electrons to coenzymes occurs at two steps.
The eight steps of the cycle are a series of redox, dehydration, hydration, and decarboxylation reactions that produce two carbon dioxide molecules, one GTP/ATP, and reduced forms of NADH and FADH2.If the transfer not occur, oxidation step of citric acid cycle does not occur.citric acid cycle produces very little ATP directly and does not directly consume oxygen.
