Question

which chemical process generates the atp produced in glycolysis?

chemiosmosis
electron transport
photophosphorylation
oxidative phosphorylation
substrate - level phosphorylation

Explanation:

• Chemiosmosis: It is related to the generation of ATP in the electron - transport chain (in mitochondria and chloroplasts), not directly in glycolysis.
• Electron transport: This is part of the process that leads to ATP generation via chemiosmosis (in aerobic respiration, mainly in mitochondria), not the process for ATP generation in glycolysis.
• Photophosphorylation: Occurs in photosynthesis (in chloroplasts) to generate ATP using light energy, not relevant to glycolysis.
• Oxidative phosphorylation: Refers to ATP generation in the electron - transport chain (mitochondria in aerobic respiration) coupled with oxidation reactions, not the process in glycolysis.
• Substrate - level phosphorylation: In glycolysis, a phosphate group is directly transferred from a phosphorylated intermediate (a substrate) to ADP to form ATP. For example, in the reaction catalyzed by pyruvate kinase, phosphoenolpyruvate transfers a phosphate group to ADP to form ATP.

Answer:

substrate - level phosphorylation
