Expert Solution

Step 1

The cellular respiration is the source of energy production in our body that metabolise glucose and ultimately responsible for the generation of ATP (adenosine triphosphate). Cellular respiration can occurs in both presence (aerobic respiration) and absence (anaerobic respiration) of oxygen.

The aerobic respiration occurs in the cytoplasm and mitochondria of the cell while anaerobic respiration occurs only within the cytoplasm of the cell.
