This is an example of an energetically couple reaction. There is one part of the raxction that is endergonic and one that is exergonic There are two parts of the reaction: o NAD+ is reduced by the removal of the hydride ion and another proton, and this gives us a change in free energy which is large and negative. Now we have NADH. o The inorganic phosphate attaches to 1-C. The product is 1-3-bisphosphaoglycerate. This step requires energy. o The overall change in energy is 6.2 kJ/mol. The redox chemistry is used to make this bond, but did not provide enough energy. This is ok in the cell because it ends up being a set up reaction. 1-3-bisphosphaoglycerate is an acylphosphate compound which is a high energy compound. It is high energy because of the bond between the 1 C and the phosphate group. When this bond is broken it is better resonance stabilized. Step 7: Conversion of high energy 1,3 BPG to 3-phosphoglycerate (3PG) Enzyme: Phosphoglycerate kinase Reaction details: 1 st of two substrate level phosphorylation
