Detailed explanation-1: -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-2: -Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products.

Detailed explanation-3: -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-4: -In aerobic respiration, one glucose molecule results in a net ATP gain of 38 ATP. It comprises ATP generated during glycolysis, the link reaction, the TCA cycle, and oxidative phosphorylation in the electron transport system.

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. During glycolysis, two ATP molecules are created inside the mitochondria and two ATP molecules are produced outside the mitochondria.
