Detailed explanation-1: -In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
Detailed explanation-2: -The final end products of cellular respiration are ATP and H2O. Glycolysis produces two pyruvate molecules, four ATPs (a net of two ATP), two NADH, and two H2O. Therefore, without the presence of oxygen, glycolysis is the only process that can occur, and only two ATP molecules may be produced for each glucose molecule.
Detailed explanation-3: -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-4: -The molecules of carbon dioxide are produced in the second stage of cellular respiration, that is, in the Krebs cycle. These molecules of carbon dioxide are carried by the circulating blood to the alveolar tissues; from there, it is expelled out of the body via a breathing mechanism.
