Answer:
The correct answer is- Cellular respiration
Explanation:
Cellular respiration is the process in which glucose is oxidized into carbon dioxide and water. This oxidation of glucose gives rise to many molecules of ATP which is the energy currency of the cell and is used to provide energy in the metabolic processes that occur in the cell.
In aerobic organisms, the catabolism of glucose occurs in two step first the glucose is oxidized to pyruvate in the glycolysis process and then pyruvate is oxidized into carbon dioxide in Kreb cycle.
The energy released in the oxidation of glucose is used to form NADH and FADH2 which provide electron source in the oxidative phosphorylation process to form ATP. Therefore the correct answer is Cellular respiration.
A single cell is often a complete organism.
