Q. The connecting link between glycolysis and kreb’s cycle in aerobic respiration is

A
RUBP
B
Acetyl COA
C
Citric acid
D
Oxalo acetic acid
Solution:
  • Acetyl-CoA (acetyl coenzyme A) is a molecule that participates in many biochemical reactions in protein, carbohydrate and lipid metabolism.

  • Its main function is to deliver the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production.

  • Acetyl-CoA, main product of the Pyruvate Dehydrogenase Complex in aerobic respiration, starts the Krebs cycle. (An irreversible reaction that is link between glycolysis and the citric acid cycle.)
