Question

Mention two ways in which food gets oxidized in organisms.

Answer 1

Dear student, food (glucose) gets oxidized in the organisms to produce energy in the following 2 ways- (1) Anaerobic respiration - it occurs in the absence of oxygen in which the glucose is broken down into an 3 carbon compound called as pyruvate. It takes place in the cytoplasm. The formed pyruvic acid is broken down into the ethanol and carbon dioxide. (2) Aerobic respiration - in the presence of oxygen the glucose molecules are broken down into the pyruvate which is further broken down into the 3 molecules of the carbon dioxide and water. Regards
