Question

Before the Krebs cycle can proceed, pyruvic acid must be converted into (a)citric acid (b)glucose (c)acetyl CoA (d) NADH

Answer 1

Pyruvic acid must be converted into c)Acetyl CoA before the Kreb cycle can proceed.

Answer 2

TCA or the citric acid cycle is a biochemical step in which the saved energy is released by the oxidation of Acetyl Co-A in the cells.

The correct answer is:

Option C. Acetyl Co-A.

This can be explained as:

• In the process, the pyruvic acid or the pyruvate is split to produce CO₂, ATP, NADH and FADH.

• The energy liberated during the TCA is the main power source for living cells.

• It is the most important step in the aerobic inhalation-exhalation process.

Therefore, pyruvic acid must be converted into acetyl CoA for the cycle to proceed.
