Using either events in the chloroplast thylakoid membrane or events in the mitochondrial inner membrane to
Inside the inner membrane of mitochondria ,oxidative phosphorylation takes place. ... Within the inner membrane of the mitochondrion there is a series of coenzymes there are a able to undergo reduction and oxidation. ... The outer membrane of the mitochondria is permeable to many substrates; the inner membrane provides a barrier to regulate uptake of substrates and output of products e. ... The inner membrane is highly folded, forming a cristae. ... The outer membrane has enzymes that are responsible for the elongation of fatty acids made in the cytosol. ... The primary particles of on the inner surface of the cristae contain the enzymes that catalyse the phosphorylation of ADP to ATP. The overall process of oxidation and reduced coenzymes, reduction of oxygen to water, and phosphorylation of ADP to ATP requires intact mitochondria, or intact sealed vesicles of mitochondrial inner membrane prepared by disruption of mitochondria ; it will not occur with solubilized preparations from mitochondria, nor with open fragments of mitochondrial inner membrane. The mitochondrial electron transport chain is a series of enzymes and coenzymes in the inner membrane, each of which is reduced by the preceding coenzyme, and in turn reduces the next, until finally the protons and electrons that have entered the chain from either NADH or reduced flavin reduce oxygen to water. ... The mitochondrial transport chain is shown below; Studies with inhibitors of specific electron carriers, and with artificial substrates that oxidize or reduce one specific carrier, permit analysis of the electron transport chain into four complexes of electron carriers. ... The hydrogen and electron carriers of the electron transport chain are arranged in sequence in the crista membrane.
