Question

*What 2 things are needed to take pyruvate to acetyl-Coenzyme*

a. Oxygen and ATP
b. Coenzyme A and NADH
c. NAD+ and Coenzyme A
d. NAD+ and CO2

Answer 1

Coenzyme A and NAD+ are the two things needed to take pyruvate to acetyl-Coenzyme A. First, pyruvate is transformed into acetyl CoA by attaching an acetyl group to coenzyme A and removing a molecule of carbon dioxide. Then, the high-energy electrons generated are picked up by NAD+ to form NADH.

Step-by-step explanation:

The two things needed to take pyruvate to acetyl-Coenzyme A are Coenzyme A and NAD+

1. First, pyruvate is transformed into an acetyl group attached to a carrier molecule of coenzyme A, forming acetyl CoA. This process involves removing a molecule of carbon dioxide from pyruvate.
2. Then, the high-energy electrons generated during this conversion are picked up by NAD+, forming NADH. NADH carries the electrons to a later pathway for ATP production.
