ATP, a major energy storing molecule in the cell, can be produced in the process(es) of
A) oxidative phosphorylation only
B) substrate level phosphorylation only
C) both in substrate level and oxidative phosphorylation
D) dephosphorylation of ADP

Question

Quizplus · Accepted Answer

ATP can be produced through both substrate level phosphorylation and oxidative phosphorylation. In substrate level phosphorylation, ATP is produced by transferring a phosphate group from a substrate molecule directly to ADP, while in oxidative phosphorylation, ATP is produced through a series of redox reactions in the electron transport chain, leading to the synthesis of ATP by ATP synthase. Dephosphorylation of ADP is not a process of ATP production, but rather the reverse process where ATP is broken down into ADP and a phosphate group, releasing energy.
