Question
Acetyl CoA forms a 6-C compound after combining with which of the following elements?
- Oxygen
- Pyruvic acid
- Citric acid
- Oxaloacetic acid
Hint:
Acetyl-Co A plays an important role in metabolism as it intersects with many of the metabolic pathways and transformations.
Its principal function is to deliver the acetyl group to the Krebs' cycle which will later oxidize for energy production in the form of ATP.
The correct answer is: Oxaloacetic acid
Acetyl Co-A forms a 6-C compound after combining with Oxaloacetic acid (OAA)
- Acetyl Co-A (2-C) formed during glycolysis combines with the oxaloacetate (4-C) of Kreb's cycle to form citrate (6-C).
- This reaction is aldol condensation which is then followed by hydrolysis and this reaction is catalyzed by citrate synthase.
