During conversion of succinyl CoA to succinic acid a molecule of GTP is formed in a reaction known as
Open in App
Solution
The correct option is B substrate level phosphorylation
In the 5th step of Krebs cycle, conversion of succinyl CoA to succinic acid (also known as succinate) occurs. Succinyl CoA is acted upon by an enzyme synthetase to form succinate (4 carbon compound). The reaction releases sufficient energy to form ATP (in plants) or GTP (in animals). GTP can form ATP through a coupled reaction. The direct synthesis of GTP/ATP from metabolites is called substrate level phosphorylation (SLP).
Phosphorylation is the addition of phosphate group to a molecule.
Oxidative phosphorylation refers to the process of phosphorylation occurring in the presence of O2.
Photophosphorylation refers to the process of phosphorylation occurring in the presence of light (photons).
Terminal oxidation refers to the process of oxidation found at the end of aerobic respiration.
