Detailed Solution

The TCA cycle, also known as the Krebs cycle or the citric acid cycle, has one substrate-level phosphorylation reaction per turn. This reaction involves the conversion of succinyl-CoA to succinate, catalyzed by the enzyme succinyl-CoA synthetase. This reaction leads to the formation of one molecule of GTP, which can then be converted to ATP by the enzyme nucleoside diphosphate kinase.

One turn of TCA cycle gives $2 C O_{2}$ molecules.

It occurs 2 times for one glucose.

Oxaloacetic acid is 4 ‘C’ compound
