(a)
Interpretation:
Number of ATP molecules that are produced by glycolysis and the number of ATP molecules produced by oxidation of glucose by aerobic respiration has to be determined.
Concept Introduction:
Glycolysis is the major metabolic pathway of glucose that occurs in the cytosol. In glycolysis, the glucose molecule breaks into two pyruvate molecule and energy is released in the form of ATP and NADH.
Aerobic respiration is the process in which fats and sugar molecules breakdown to produce energy in the presence of oxygen. In aerobic respiration, oxygen is used as a reactant and produces ATP, carbon dioxide, and water. Different stages of aerobic respiration occur in a different compartment of mitochondria. The stages of aerobic respiration are glycolysis, the Krebs cycle, and oxidative phosphorylation.
(b)
Interpretation:
The pathway that produces more ATP has to be explained.
