In glycolysis, each glucose molecule is broken down into
|
|
six molecules of carbon dioxide
|
|
|
four molecules of ATP
|
|
|
two molecules of pyruvic acid
|
|
|
two molecules of ATP
|
Explanation:
Detailed explanation-1: -Glycolysis is a linear metabolic pathway of enzyme-catalyzed reactions that convert glucose into two molecules of pyruvate in the presence of oxygen or into two molecules of lactate in the absence of oxygen.
Detailed explanation-2: - During glycolysis, glucose is broken down in ten steps to two molecules of pyruvate, which then enters the mitochondria where it is oxidised through the tricarboxylic acid cycle to carbon dioxide and water. Glycolysis can be split into two phases, both of which occur in the cytosol.
Detailed explanation-3: -In glycolysis, one molecule of glucose (C6H12O6) forms two molecules of pyruvic acid (CH3COCOOH).
