Krebs Cycle Schematic Overview — NEET Biology
📚 Practice ConceptGive the schematic representation of an overall view of Krebs' cycle.
Which of the following statements about direct ATP synthesis (substrate-level phosphorylation) in respiration are NOT correct? S1: In glycolysis, a total of 4 ATP molecules are directly synthesized, but a net of 2 ATP is available. S2: The conversion of succinyl-CoA to succinic acid in the Krebs cycle directly produces 2 ATP molecules per glucose. S3: The overall net ATP production via substrate-level phosphorylation during aerobic respiration of one glucose molecule is 6 ATP. S4: The step involving the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate is an example of substrate-level phosphorylation. S5: Fermentation produces ATP solely through the reoxidation of NADH+H+ to NAD+ in the absence of oxygen.
