WebAll organisms produce a phosphate compound, ATP, which is the universal energy currency of life. In photophosphorylation, light energy is used to pump protons across a biological membrane, mediated by flow of electrons through an electron transport chain. This stores energy in a proton gradient. As the protons flow back through an enzyme called ... WebThe citric acid cycle is a closed loop; the last part of the pathway reforms the molecule used in the first step. The cycle includes eight major steps. In the first step of the cycle, acetyl \text {CoA} CoA combines with a four-carbon acceptor molecule, oxaloacetate, to form a six-carbon molecule called citrate.

Cyclic Electron Flow - CliffsNotes

WebAs the electron flow occurs, protons are flowing across the inner membrane into the intermembrane space. Components of the Electron Transport Chain When electrons flow down the energy gradient from NADH to O2, the four protein complexes that catalyze the redox reaction are: Complex I = NADH-Q reductase complex WebThe first step is similar in both cyclic and non-cyclic electron flow.
