In which of the following reactions is pyruvate degraded and combined with coenzyme A to form acetyl CoA?

A) Formation of acetyl CoA
B) Citric acid cycle
C) Glycolysis
D) Decarboxylations
E) Electron transport and chemiosmosis

Coenzyme A

A coenzyme involved in the synthesis and oxidation of fatty acids, and the oxidation of pyruvate in the citric acid cycle.

Pyruvate

A key intermediate compound in cellular respiration and metabolism, resulting from the glycolysis of glucose.

Acetyl CoA

Acetyl CoA is a central metabolite in energy metabolism, acting as a substrate for the citric acid cycle and involved in the synthesis and oxidation of fatty acids.
