NEET BIOLOGY

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: -The energy produced by the mitochondria is stored as potential energy in molecules called adenosine triphosphate (ATP). The main chemical produced in cellular respiration is ATP.

Detailed explanation-3: -Most of the adenosine triphosphate (ATP) synthesized during glucose metabolism is produced in the mitochondria through oxidative phosphorylation. This is a complex reaction powered by the proton gradient across the mitochondrial inner membrane, which is generated by mitochondrial respiration.

Detailed explanation-4: -Mitochondria have an important role in cellular respiration through the production of ATP, using chemical energy found in glucose and other nutrients.

Detailed explanation-5: -The most important process in stage 2 of the breakdown of food molecules is the degradation of glucose in the sequence of reactions known as glycolysis-from the Greek glukus, “sweet, ” and lusis, “rupture.” Glycolysis produces ATP without the involvement of molecular oxygen (O2 gas).
