Respiration, chemiosmosis and oxidative phosphorylation

WebFeb 3, 2024 · This flow of hydrogen ions across the membrane, called chemiosmosis, must occur through a channel in the membrane via a membrane-bound enzyme complex called ATP synthase (Figure 7.2. 7 ). The tendency for movement in this way is much like water accumulated on one side of a dam, moving through the dam when opened. WebThis flow of hydrogen ions across the membrane through ATP synthase is called chemiosmosis. Chemiosmosis ( Figure 4.15 c) is used to generate 90 percent of the ATP made during aerobic glucose catabolism. The result of the reactions is the production of ATP from the energy of the electrons removed from hydrogen atoms. new homes new bern nc

The actual production of ATP in cellular respiration takes place through the process of chemiosmosis (see Chapter 4). Also, two ATP molecules are produced through glycolysis, so the net yield is 38 molecules of ATP. These ATP molecules may then be used in the cell for its needs. new homes newark new jersey

"WebDec 24, 2024 · Overall, the process of glycolysis produces a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules for the cell to use for energy. Following the conversion of glucose to pyruvate, the glycolytic pathway is linked to the Krebs Cycle, where further ATP will be produced for the cell’s energy needs.
