This Concept Map, created with IHMC CmapTools, has information related to: 15.2.2 Krebs Cycle, 15.2.2: KREBS CYCLE/CITRIC ACID CYCLE ????, 2 ATP ???? 6 NADH produced,three per acetyl CoA. 2 FADH2 produced,one per acetyl CoA. 2 ATP produced,one per acetyl CoA., Link reaction: pyruvate to acetyl CoA ???? 2 NADH, 2 NADH ???? Nil, 2 NADH ???? 2 ATP, Glycolysis ???? 2 NADH, STEP 2 The enzyme aconitase catalyses the dehydration of citrate.The same enzyme then catalyses addition of water molecule to the cis-aconitate, converting it to isocitrate.The net effect of these two steps is the isomerisation of citrate to isocitrate. ????, STEP 1 The starting point of Krebs cycle is a reaction involving acetyl CoA. The acetyl CoA (2C) combines with oxaloacetate (4C) to form a molecule of citrate (6C) or citric acid. It is catalysed by the enzyme citrate synthase. ???? STEP 2 The enzyme aconitase catalyses the dehydration of citrate.The same enzyme then catalyses addition of water molecule to the cis-aconitate, converting it to isocitrate.The net effect of these two steps is the isomerisation of citrate to isocitrate., OR, ???? STEP 1 The starting point of Krebs cycle is a reaction involving acetyl CoA. The acetyl CoA (2C) combines with oxaloacetate (4C) to form a molecule of citrate (6C) or citric acid. It is catalysed by the enzyme citrate synthase., Nil ???? 2 NADH produced,one per pyruvate., 6 NADH 2 FADH2 ???? 2 ATP, 15.2.2: KREBS CYCLE/CITRIC ACID CYCLE a summary of ATP,NADH and FADH2 yield from glycolysis to Krebs cycle PROCESS REDUCED COENZYME ATP YIELD PER REMARKS GLUCOSE MOLECULE, 2 ATP ???? Produced 4 ATP,minus 2 ATP utilised in iniating glycolysis,net yield is 2 ATP., Krebs Cycle ???? 6 NADH 2 FADH2
