Detailed explanation-1: -Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body. There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.

Detailed explanation-2: -Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. The energy released is used to create a chemiosmotic potential by pumping protons across a membrane. This potential is then used to drive ATP synthase and produce ATP from ADP and a phosphate group.

Detailed explanation-3: -The majority of ATP synthesis takes place within the mitochondrial matrix during cellular respiration, with each molecule of glucose oxidized creating around 32 A T P molecules. Energy is liberated and used to pump protons out of the matrix as electrons flow down the chain, resulting in a gradient.
