The image below shows the citric acid cycle. Reaction 5 is the substrate-level phosphorylation. Select the correct statement about this reaction Acetyl-CoA Condensation CH₂-C-S-CoA H₂O COA-SH citrate CH₂-COO™ synthase 0-C-COO HO-C-COO™ 2a Dehydrogenation CH₂-COO Dehydration Citrate Citric acid H₂O aconitase cycle HO-CH Malate Hydration NADH H₂O Fumarate CH HC coo Dehydrogenation malate Coo- dehydro- genase CH₂ COO™ fumarase çoo CH₂-COO™ Oxaloacetate FADH₂ succinate dehydrogenase CH₂-COO™ CH₂ coo Succinate succinyl-CoA synthetase CH₂-COO CoA-SH CH₂ GDP C-S-COA (ADP) +P₁ Substrate-level phosphorylation Figure 16-7 Lehninger Principles of Biochemistry, Fifth Edition 2008 W.H.Freeman and Company GTP (ATP) a-ketoglutarate dehydrogenase Succinyl-CoA CH₂COO c-coo c-coo aconitase CO₂ cis-Aconitate -H₂0 (2b Hydration Isocitrate Oxidative decarboxylation complex CH₂-COO CoA-SH So COO™ Oxidative decarboxylation CH₂-COO™ H-C-COO™ HO-CH isocitrate dehydrogenase coo CO₂ a-ketoglutarate
O The reaction is NADH dependent A phosphate group is taken from the Coenzyme A substrate The reaction is part of 'acetyl-CoA catabolism' phase 1. O The reaction is part of 'regeneration of oxaloacetate' phase 2. The reaction is a more efficient source of ATP compared to oxidative phosphorylation.
