Choose a False statement regarding step 6 of glycolysis
| Oxidation and phosphorylation are decoupled |
| The oxidant is NAD+ |
| ATP not required for phosphorylation |
| Reaction is endergonic, but the product is consumed in the next step to move the pathway forward |
| Rationale: generation of a high-energy phosphate compound which allows for net production of ATP via glycolysis |
| none of the answers are correct |
