write the tricarboxylic acid cycle of plant respiration
Dear student,
The tricarboxylic acid cycle of plant respiration is as follows:
1)Acetyl group condenses with oxaloacetic acid and water to form citric acid.It is catalyzed by the enzyme citrate synthase.
2)Isomerisation of citrate occurs in isocitrate.
3)It is followed by two successive decarboxylation reactions which lead to the formation of ɑ ketoglutaric acid and is followed by the formation of succinyl CoA.
4)Succinyl acid is formed from succinyl CoA and it is known as substrate-level phosphorylation.With this in a couple reaction, GTP is converted into GDP, simultaneously synthesizing ATP from ADP.
5)The conversion of one molecule of pyruvate into acetyl CoA yields 1 molecule of carbon dioxide and 1 molecule of NADH.
6)One Krebs cycle yields 2CO2+3NADH+1FADH2+1ATP
7 )The overall reaction is as follows:
Pyruvic acid+4NAD++FAD++2H2O+ADP+Pi→3CO2+4NADH+4H++FADH2+ATP.This reaction occurs in the mitochondrial matrix.
8)For continuous oxidation of acetyl CoA, two things are required,
1)there should be continuous replenishment of oxaloacetic acid
2)there should be the regeneration of NAD+ and FAD+ from NADH and FADH2.
The tricarboxylic acid cycle is shown below.
