complex III (ubiquinone to cytochrome c)

The transfer of electrons from ubiquinol to cytochrome c that occurs during oxidative phosphorylation, mediated by the multisubunit enzyme known as complex III.

mitochondrial electron transport, cytochrome c to oxygen

The transfer of electrons from cytochrome c to oxygen that occurs during oxidative phosphorylation, mediated by the multisubunit enzyme known as complex IV.

The chemical reactions and physical reactions involving ferredoxin, any simple, nonenzymatic iron-sulfur protein that is characterized by having equal numbers of atoms of iron and labile sulfur. Iron and sulfur atoms are present in one or two clusters of two or four atoms of each.

The process of transferring reducing equivalents from the cytosol into the mitochondria; NADH is used to synthesise glycerol 3-phosphate in the cytosol; this compound is then transported into the mitochondria where it is converted to dihydroxyacetone phosphate (DHAP) using FAD; DHAP then returns to the cytosol to complete the cycle.

The acetylation of the N-terminal methionine of proteins to form the derivative N-acetyl-L-methionine.

Any process that modulates the frequency, rate or extent of glycolysis.

Any process that modulates the frequency, rate or extent of gluconeogenesis, the formation of glucose from noncarbohydrate precursors, such as pyruvate, amino acids and glycerol.

The anaerobic enzymatic conversion of organic compounds, especially carbohydrates, to simpler components, especially to ethyl alcohol, yielding energy in the form of adenosine triphosphate (ATP).

The formation from simpler components of glycerol, 1,2,3-propanetriol, a sweet, hygroscopic, viscous liquid, widely distributed in nature as a constituent of many lipids.

reduced nicotinamide adenine dinucleotide oxidation

Any of the processes that result in the oxidation of reduced nicotinamide adenine dinucleotide, NADH, to the oxidized form, NAD.

The transport of electrons from an electron donor to an electron acceptor.

The phosphorylation of ADP to ATP that accompanies the oxidation of a metabolite through the operation of the respiratory chain. Oxidation of compounds establishes a proton gradient across the membrane, providing the energy for ATP synthesis.
