Detailed explanation-1: -During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
Detailed explanation-2: -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.
Detailed explanation-3: -Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.
Detailed explanation-4: -During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP.
Detailed explanation-5: -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.
