Question

Why is oxidation catalyzed by glyceraldehyde 3-phosphate dehydrogenase spontaneous? Acyl-phosphate formation is promoted by inorganic phosphate by increasing the phosphoryl-transfer potential. The free energy of the thioester intermediate is lower than that of GAP, NAD+, and H2O. The thioester intermediate is more stable than 1,3-BPG. The free energy of the thioester intermediate is higher than that of GAP, NAD+, and H2O. The free energy of the thioester intermediate is lower than that of 1,3-BPG.

Step 1

This reaction is spontaneous because it is exergonic, meaning it releases energy. Second, the formation of the thioester intermediate during this reaction is a key step. A thioester is a type of compound that has a high-energy bond, which makes it less stable and Show more…
