HUMAN NUTRITION

Detailed explanation-1: -The process is carried out by six enzymes. Two pyruvate, two ATP, and two NADH molecules are the end products of the process.

Detailed explanation-2: -Pyruvic acid is the end product of glycolysis. Two molecules of pyruvic acid are generated by the partial oxidation of one glucose molecule.

Detailed explanation-3: -Anaerobic glycolysis is the main pathway responsible for supplying the cell with both ATP and nicotinamide adenine dinucleotide (reduced) (NADH), a cofactor for methaemoglobin reductase, the enzyme that catalyses the reduction of methaemoglobin to functional haemoglobin (see Fig. 27.2).

Detailed explanation-4: -In anaerobic conditions, pyruvate converts to lactate through anaerobic glycolysis. Anaerobic respiration results in the production of 2 ATP molecules.
