Important Questions on Respiration in Plants

Trace the fate of glycolysis end products in anaerobic respiration.







\nThe following are the series of chemical reactions:
\n\nCondensation: The Kerb’s cycle starts with the condensation of Acetyl-CoA with oxaloacetic acid (OAA) and water to yield citric acid. The reaction is catalysed by the enzyme citrate synthase and a molecule of CoA is released.
\n\n\n\n\nDehydration and Hydration: Citrate is then isomerised to isocitrate by two consecutive reactions of dehydration and hydration both the reactions being mediated by the same enzyme Aconitase.
\n\n\n\t
\n\n- Dehydration: Citric acid → Cis-aconitase acid + H2O
\n\t- Hydration: Cis-aconitase +acid Aconitase → Isocitric acid
\nOxidation: This is the oxidative reaction of the TCA cycle mediated by the enzyme isocitric dehydrogenase.
\n\n\n\t
\n- NAD+ is reduced to yield NADH+H.
\n\t- Isocitric acid + NAD+→ Oxalosuccinic acid + NADH+H
\n
\n\n\nDecarboxylation:
\n\n\n\t
\n\n- Oxalosuccinic acid Oxalasuccinic decarboxylase → u-Ketoglutaric acid + CO2
\nOxidative decarboxylation (oxidation I):
\n\n\n\t
\n\n- a-Ketoglutaric acid + NAD +CoA → a-ketoglutaric dehydrogenase Succinyl COA + NADH + CO
\nCleavage:
\n\n\n\t
\n- Succinyl CoA+ ADP+Pi → Succinic thiokinase Succinic acid + ATP + COA
