In Krebs's cycle, reaction representing substrate level phosphorylation is
1 G3p 1, 3 DPGA
2 Succinyl CoA Succinic acid
3 Succinic acid Fumaric acid
4 - ketoglutarate Succinyl CoA
Explanation:
Exp:B Substrate level phosphorylation is a type of cellular respiration that occurs directly in the substrate, cutouts the need for an electron transport chain. In the case of kreb's cycle, the substrate is succinyl Co A. When succinyl Co A is converted to succinic acid, a high-energy phosphate group is transferred from succinyl Co-A to ADP, forming ATP.

In plants, cycle takes place in
1 Mesophyll cells
2 Bulliform cells
3 Companion cells
4 Bundle sheath cells
Explanation:
Exp:D In plants, cycle takes place in bundle sheath cells. and cycle is a type of dark reaction of photosynthesis. The cell present between the upper and lower epidermis are called the mesophyll cells. In plants the fixation of carbon happens in the mesophyll cells, where as the cycle or Calvin cycle occurs in the bundle sheath. In this way, the plants are able to reduce the water loss to the transpiration. Sugarcane, corn and sorghum are example of plants.

In the following reaction, identify and respectively : Pyruvic acid
1 Water, Acetyl CoA
2 Acetyl CoA, Pyruvate dehydrogenase
3 Pyruvate dehydrogenase, Acetyl CoA
4 Pyruvate dehydrogenase, Oxalo-acetic acid
Explanation:
Exp:C The pyruvate dehydrogenase bring about decarboxylation of pyruvic acid to produce molecule of acetyl CoA which is further utilized in the Krebs cycle. The krebs cycle or TCA cycle (tricarboxylic acid cycle) or citric acid cycle is a series of enzyme catalysed reactions that occur in the mitochondrial matrix, where acetyl - CoA is oxidized to form carbon dioxide and coenzymes are reduced, which generate ATP in the electron transport chain.

A competitive inhibitor of succinic dehydrogenase is :
1-ketoglutarate
2 malate
3 malonate
4 oxaloacetate
Explanation:
Exp:C An inhibitor is a type of chemical compound that supply enzyme activity. A competitive inhibitor shows structural similarity with the substrate and prevents the binding of the substrate to the enzyme.The competitive inhibitor of succinic dehydrogenase is malonate. It resembles the substrate succinate and binds to the active site of the enzyme, thereby inhibiting enzyme activity.
