What produces ATP process?

The process human cells use to generate ATP is called cellular respiration. It results in the creation of 36 to 38 ATP per molecule of glucose. The two ATP-producing processes can be viewed as glycolysis (the anaerobic part) followed by aerobic respiration (the oxygen-requiring part).

How is ATP synthesized in respiration?

ATP is synthesized by the ATP synthase enzyme when the chemiosmotic gradient is used to drive the phosphorylation of ADP. The electron transfer is driven by the chemical energy of exogenous oxygen and, with the addition of two protons, water is formed.

Where is ATP synthesized in glycolysis?

Substrate -level phosphorylation, where a substrate of glycolysis donates a phosphate to ADP, occurs in two steps of the second-half of glycolysis to produce ATP. The availability of NAD+ is a limiting factor for the steps of glycolysis; when it is unavailable, the second half of glycolysis slows or shuts down.

Which process is responsible for ATP molecule energy release oxidation or reduction?

This process is known as phosphorylation. Glucose can be converted into Glucose-6-phosphate by the addition of the phosphate group from ATP. ATP serves as the biological energy company, releasing energy for both anabolic and catabolic processes and being recharged by energy generated from other catabolic reactions.

Where is ATP synthesized in cellular respiration?

mitochondrial matrix
The majority of ATP synthesis occurs in cellular respiration within the mitochondrial matrix: generating approximately thirty-two ATP molecules per molecule of glucose that is oxidized.
