Question

After glycolysis, fate of glucose in mitochondrial matrix is

• A. Hydrolysis
• B. Oxidative decarboxylation
• C. Reduction
• D. Oxidation

Answer 1

The correct option is B Oxidative decarboxylation

After glycolysis, the end product pyruvic acid undergoes Krebs cycle but before that, it has to go through link reaction. The link reaction occurs in mitochondrial matrix and converts pyruvic acid to acetyl CoA through the pyruvate dehydrogenase complex. Such a reaction is called oxidative decarboxylation. Hydrogen and carbon dioxide are released.

So, the correct answer is 'Oxidative decarboxylation'.
