The ATP made during glycolysis is generated by electron transport: substrate-level phosphorylation and chemiosmosis. Photophosphorylation involves the oxidation of NADH to NAD+.

The ATP-generating metabolic process whereby one organic compound (the energy source) serves as a donor of electrons and another organic compound plays as an electron acceptor is formally called: A. Fermentation B. Aerobic Cellular Respiration C. Anoxygenic photosynthesis D. Oxygenic photosynthesis E. Oxidative phosphorylation 2. The vast majority of ATP produced by microorganisms in Cellular Respiration occurs through: A. The Substrate-level phosphorylation B. Entner-Doudoroff pathway C. Embden-Meyerhof pathway D. Glycolysis E. Oxidative Phosphorylation (ETS) 3. Photophosphorylation can occur in the absence of Chlorophyll by employing light-absorbing compounds, like _______________, by Cyanobacteria and _______________ by halophile Archaea: A. Phycobilisomes, Bacteriorhodopsin B. Bacteriorhodopsin, Phycobilisomes C. Chlorosomes, Phycobilisomes D. Bacteriorhodopsin, Chlorosomes E. Bacteriochlorophyll a, Phycobilisomes

The most direct source of energy that is used to power ATP synthesis in chemiosmosis is the flow of electrons through the electron transport chain. As electrons are passed along the chain, their energy is used to pump protons (H+) across the inner mitochondrial membrane. This creates an electrochemical gradient, with a higher concentration of protons on one side of the membrane. The energy released from the movement of electrons is then used to phosphorylate ADP to ATP. In glycolysis, a glucose molecule is broken down into two pyruvate molecules. This process produces a net gain of 2 NADH and 4 ATP molecules. The pyruvate can then enter the citric acid cycle, where it is further oxidized and produces more NADH and ATP.
