Question

What is the first intermediate compound in the Krebs cycle

Answer 1

Answer:

pyruvate

Explanation:

Pyruvate, the product of glycolysis, is  converted to acetyl-CoA, the starting material  for the citric acid cycle, by the pyruvate  dehydrogenase complex. Acetyl-CoA donates its acetyl group  to the four-carbon compound oxaloacetate to form the  six-carbon citrate.

Answer 2

Answer:

Pyruvate is the first intermediate compound in the Krebs cycle.

Explanation:

• Pyruvate is the product formed from the glycolysis. In the Krebs cycle the compound pyruvate is converted into acetyl CoA.

• This is carried out into three steps. The 'Krebs cycle' is also called as the 'citric acid cycle' due to this reason.

• Multiple molecules of this pyruvic acid are used in yielding the high energy for the process. These chemical reactions are carried out by all anaerobic organisms.
