Exp:B GTP is formed by substrate - level phosphorylation is the Kreb cycle. Substrate level phosphorylation is a type of ATP synthesis that occurs directly form the energy released by chemical reaction. In the Kreb cycle, GTP is formed during the conversion of succinyl - Co-A to succinate. This reaction is catalyzed by the enzyme succinyl - CoA synthetase, and it requires the hydrolysis of GDP.

Which one is not correct about Krebs' cycle?
1 It occurs in mitochondria.
2 It starts with six carbon compound
3 It is also called citric acid cycle.
4 The intermediate compound which links glycolysis with Krebs' cycle is malic acid.
Explanation:
Exp:D The intermediate compound that links glycolysis with krebs cycle is acetyl-CoA, not malic acid. Acetyl-CoA is formed from the oxidative decarboxylation of pyruvate, which is the end product of glycosis. Acetyl-CoA then enters the Krebs cycle by combining with oxaloacetate to form citrate, a six carbon compound. Malic acid is one of the intermediates of the Krebs cycle.

Which of the following is true for TCA cycle is eukaryotes?
1 takes place in mitochondrion
2 produces no ATP
3 takes place in Golgi complex
4 independent of electron transport chain
Explanation:
Exp:A TCA cycle or Krebs cycle takes place in the mitochondria in the cell. The number of ATP molecules produced in the Krebs cycle is 2ATP.

Krebs cycle was discovered by Krebs in pigeon muscles in 1940. Which step is called gateway stem/link reaction/transition reaction in respiration?
1 Glycolysis
2 Formation of acetyl-CoA
3 Citric acid formation
4 ETS terminal oxidation
Explanation:
Exp:B The gateway step , link reaction, or transition reaction is the step in respiration that links glycolysis to the Krebs cycle. This step is the formation of acetylCoA from pyruvate. Acetyl CoA is the substrate for the Krebs cycle and it is also the molecule that carries energy from glycolysis to the Krebs cycle.
