Detailed explanation-1: -During respiration, chemical energy is used and is converted into mechanical energy. Cellular respiration is the process of transforming chemical energy into forms usable by the cell or organism.

Detailed explanation-2: -Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.

Detailed explanation-3: -(1) Electric cell converts chemical energy into electrical energy.

Detailed explanation-4: -The citric acid cycle produces 36 ATP molecules. So, in aerobic respiration, a total of 38 molecules of ATP are created, with 2 ATP molecules formed outside the mitochondria.
