Question

Anaerobic respiration following glycolysis is

• A. Oxidative phosphorylation
• B. Krebs cycle
• C. Fermentation
• D. Both A and B

Answer 1

The correct option is C Fermentation

Following glycolysis, if the oxygen is available, end products of glycolysis directly enter Krebs' cycle for further oxidation and energy production. In anaerobic conditions, it chooses to get fermented and the end product is another organic substance which is incompletely oxidised, producing less energy.

So, the correct answer is 'Fermentation'.
