A type ofphosphorylationin which the phosphoryl group is transferred from a donorcompound(a phosphorylated reactive intermediate) to the recipientcompound Supplement Substrate-level phosphorylation is one of the ways in which a phosphate group is introduced into amolecule. Another isoxidative phosphorylation...
Anaerobic chemoorganotrophs can use a number of compounds other than oxygen as the terminal electron acceptor. For fermentative organisms, however, ATP is generated through substrate-level phosphorylation and oxidation of electron donors coupled to the reduction of electron carriers like Nicotinamide ...
A small amount of ATP is generated during glycolysis and the TCA cycle via a process called substrate level phosphorylation. Once electron carriers reach the ETC, however, a large amount of ATP is created through a process called oxidative phosphorylation. What are the main redox reactions in ...
From glycolysis alone, the net ATP is two (from substrate-level phosphorylation). By oxidative phosphorylation, the net ATP is about 34. Thus, the total net ATP per glucose is about 36.1 In the absence of adequate oxygen, glycolysis does not proceed to oxidative phosphorylation. Rather, ...
Regulation of Metabolic Pathways To maintain a living status, cells and organisms always persist in a dynamic steady state. This means at the molecular level, that for each metabolic reaction in a pathway, the substrate is provided by the preceding reaction at the same rate at which it is con...

Glucose is the most common form of monosaccharide that the cell uses to synthesize ATP via substrate-level phosphorylation (glycolysis) and/or oxidative phosphorylation (involving redox reactions and chemiosmosis). Monosaccharides that are not yet needed are stored as energy-rich polysaccharides. In plan...
one of itsphosphategroups. The energy released in the process is used to power up many vital cellular processes. ADP reconverts to ATP by the addition of a phosphate group to ADP. This occurs in processes such as substrate-level phosphorylation, oxidative phosphorylation, and photophosphorylation....
