|
|
Glycolysis and the ETC
|
Explanation:
Detailed explanation-1: -Acetyl-CoA or Acetyl-Coenzyme A is the connection between glycolysis and the Krebs cycle.
Detailed explanation-2: -NAD molecule is reduced to form NADH. It takes place in the presence of enzyme pyruvate dehydrogenase. This reaction is known as the connecting link between glycolysis and Krebs cycle.
Detailed explanation-3: -The glycolysis occurs in cytoplasm producing pyruvic acid, whereas Krebs cycle occurs in mitochondria and requires acetyl CoA. Thus acetyl CoA produced with the help of pyruvate dehydrogenase acts as a link between glycolysis and Krebs cycle.
