Photophosphorylation Vs Oxidative Phosphorylation. Web in oxidative phosphorylation, the energy comes from electrons produced by oxidation of biological molecules. They don't happen at the same time.
Oxidative Phosphorylation
In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. Photosynthetic phosphorylation and oxidative phosphorylation appear to be generally similar processes, both consisting of atp synthesis coupled to the transfer of electrons along an electron carrier chain. Web photophosphorylation occurs during photosynthesis and oxidative phosphorylation during cellular respiration. The chemiosmosis of h+ ions down the concentration gradient through the pores of atpsynthase then supplies the energy needed to phosphorylate adp into atp , which is. Web oxidative phosphorylation is made up of two closely connected components: In oxidative phosphorylation, the energy comes from electrons produced by oxidation of biological molecules. The electron transport chain and chemiosmosis. In photosynthesis, the energy comes from the light of the sun. Web so the entire process is called oxidative phosphorylation. Web almost all aerobic organisms (organisms that require oxygen to live) use oxidative phosphorylation, in one way or another, to produce the basic energy currency of the cell needs to function:
All green cells on illumination accomplish photophosphorylation whereas all living cells perform oxidative phosphorylation. Photons from the sun interact with chlorophyll molecules in reaction centers in the chloroplasts (figures \(\pageindex{1}\) and \(\pageindex{2}\)) of plants or membranes of. A) both contain cytochromes and flavins in their electron carrier chains. Oxidative phosphorylation involves the reduction of o2 to h 2 o with electrons donated by nadh and fadh 2 in all aerobic organisms. 2) of plants or membranes of photosynthetic bacteria. Web the citric acid cycle, where acetyl coa is modified in the mitochondria to produce energy precursors in preparation for the next step. In both cases electrons are transferred through a series of. Web 11.3.4 phosphorylation in eukaryotes, oxidative phosphorylation occurs in mitochondria, while photophosphorylation occurs in chloroplasts to produce atp. Which of the following is not true of both processes? They don't happen at the same time. A primary difference is the ultimate source of the energy for atp synthesis.
