Kreb's cycle was discovered by Krebs in ...

Kreb's cycle was discovered by Krebs in pigeon muscles in 1940. Which step is called gateway step. Link reaction/transition reaction in respiration.

A

Glycolysis

B

Formation of acetyl-coA

C

Citric acid formation

D

ETS terminal oxidation.

Text Solution

Verified by Experts

The correct Answer is:
B
If `O_(2)` is not available pyruvic acid undergo anaerobic respiration fermentation, but under aerobic condition the pyruvic acid enter into mitochondria and converted to Acetyl Co-A. Acetyl CoA functions as substrate extrant for krebs cycle. So, a connecting link between the glycolysis and krebs cycle.
