Name the enzyme that converts pyruvate into Acetyl CoA.
Explanation
Pyruvate Dehydrogenase is the enzyme responsible for converting pyruvate into Acetyl CoA. This enzyme plays a crucial role in the process of cellular respiration, specifically in the link reaction between glycolysis and the Krebs cycle. During this conversion, pyruvate undergoes decarboxylation and is transformed into Acetyl CoA, which is then utilized in the Krebs cycle to produce energy in the form of ATP. Pyruvate Dehydrogenase is a complex enzyme consisting of multiple subunits and requires various cofactors for its activity.Rate this question:

In the Citric Acid Cycle, what is Pyruvate converted into?
Explanation
In the Citric Acid Cycle, pyruvate is converted into Acetylcoenzyme A, also known as Acetyl coenzyme A or Acetyl CoA. This process occurs in the mitochondria and is a crucial step in the metabolism of carbohydrates and fats. Acetyl CoA then enters the next stage of the cycle, where it is further broken down to produce energy in the form of ATP.Rate this question:
