Question

Substrate-level phosphorylation occurs in ______.

पर्याय

• Mitochondria

• Chloroplast

• Cytosol

• Lysosome

Answer 1

Substrate-level phosphorylation occurs in Mitochondria.

Explanation:

Substrate-level phosphorylation is a metabolic reaction in which a phosphate group from a substrate is transferred directly to ADP or GDP, resulting in the generation of ATP or GTP. Phosphorylation of substrates takes place in the cytoplasm of cells (glycolysis) and in the mitochondria (Krebs cycle).
