Detailed explanation-1: -In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step. The goal of cellular respiration is to capture this energy in the form of ATP.

Detailed explanation-2: -What is the purpose of cellular respiration? Cellular respiration is used to generate usable ATP energy in order to support many other reactions in the body. ATP is particularly important for energetically unfavorable reactions that would otherwise not occur without an energy input.

Detailed explanation-3: -The main purpose of respiration is to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood.

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.

Detailed explanation-5: -One glucose molecule is metabolised to yield 38 ATP molecules during cellular respiration. The electron transport system produces 34 molecules of ATP out of a total of 38 molecules.
