Explain how ATP is made in Glycolysis, Krebs Cycle, and the Electron Transport Chain
Substrate level phosphorylation occurs in glycolysis and the krebs cycle when the intermediate molecules contain
Oxidative phosphorylation can produce between 32-34 ATP molecules per molecule of glucose
NADH and FADH2 transfer electrons to protons in the inner mitochondrial membrane, when this happens, energy is released, the energy is used by the proteins to pump h + ions from the matrix to the intermembrane space
The electrons are passed from the protein to protein in the Etc, as the occurs, energy is released and the proteins use this energy to pump additional h+ from the matrix to the intermembrane space establishing a concentration gradient.
Because of the concentration gradient, h+ can diffuse through ATP synthase, providing the energy to phosphorylate ADP to form ATP.
State instances of when molecules are oxidized or reduced in glycolysis, the link reaction, the Krebs cycle, and the electron transport chain:
