Answer:

190 ATP molecules

Step-by-step explanation:

Cellular respiration is the process whereby energy (ATP) is obtained in the cells of living organisms by breaking down glucose molecules. Cellular respiration can either be aerobic or anaerobic depending on whether oxygen is present or not.

In the presence of oxygen, aerobic respiration, which consists of three stages namely: glycolysis, Krebs cycle and oxidative phosphorylation, is employed. Per glucose molecule;

- Glycolysis produces 2 ATP molecules,

- Krebs cycle produces 2 ATP molecules

- Oxidative phosphorylation produces 34 ATP molecules

Hence, in total, 38 ATP molecules is produced per glucose molecule in aerobic respiration. According to the question, 5 molecules of glucose will yield 5 × 38 = 190 molecules of ATP.
