Question

Quizplus · Accepted Answer

The process described in the question, where a phosphate group is directly transferred from 1,3-diphosphoglycerate to ADP, is known as direct substrate phosphorylation. This process generates ATP without the involvement of an electron transport chain, which is characteristic of oxidative phosphorylation (E). Oxidation (A) and reduction (C) involve the transfer of electrons, not phosphate groups, and transamination (D) involves the transfer of an amino group.
