Final answer:
The enzyme glyceraldehyde-3-phosphate dehydrogenase transfers a phosphate group from Glyceraldehyde-3-phosphate (GAP) to produce 1,3-bisphosphoglycerate (1,3BPG) in the glycolysis pathway.
Step-by-step explanation:
The enzyme that transfers a phosphate group between Glyceraldehyde-3-phosphate (GAP) and 1,3-bisphosphoglycerate (1,3BPG) is called glyceraldehyde-3-phosphate dehydrogenase. During glycolysis, this enzyme plays a crucial role by catalyzing the oxidation of GAP, transferring high-energy electrons to NAD+ to produce NADH. Simultaneously, it facilitates the addition of a second phosphate group to the oxidized GAP, resulting in the production of 1,3BPG. This process also involves the enzyme phosphoglycerate kinase, which then catalyzes the transfer of a high-energy phosphate from 1,3BPG to ADP, thus forming ATP and 3-phosphoglycerate.
