Question

What is not directly produced in the Kreb Cycle?

Answer 1

Answer:

The correct answer will be option-A.

Explanation:

Krebs cycle or tri-carboxylic cycle a series of cyclic chemical reactions taking place in the cell which helps in oxidation of the acetyl-CoA to form energy molecules as reducing energy equivalents.

It is the phase of the aerobic respiration which produces reducing equivalents like NADH and FADH₂ with other by-products like two carbon dioxide (CO₂). It also produces one Guanosine triphosphate (GTP) molecule.

The hydrogen ions are not produced in the cycle directly but are utilized in the conversion of the NAD⁺ to NADH and 2 H⁺ ions used in FAD to FADH₂.

Thus, option-A is the correct answer.
