Metabolism b. Catabolic c. Anabolism d. Reduction e. Oxidative

Explanation / Answer

Ans-1 Option-(a) Compeitative inhibitor.

competitive inhibitors function by binding reversibly to the active site of the enzyme which prevents the binding of the substrate to the active site of an enzyme. Both competes for binding to an active site.

Ans-2 Option (b)- Substrate level phosphorylation

Substrate level phosphorylation is a metabolic reaction in which formation of ATP or GTP occurs by direct transfer of phosphoryl group to ADP or GTP from another phosphorylated compounds.

Ans-3 option (a) - Feedback inhibition

Feedback inhibition or end product inhibition is the process in which end product of the pathway inhibit the enzyme to stop further reaction as the product is sufficient.

Ans-4 Option (c)- oxidative phosphorylation

Oxidative phosphorylation is a process in which electron from passes through ETC couples this electron transfer with the transfer of protons (H+ ions) across a membrane.

Ans-5 option (d) Respiration

In respiration the glucose is finally broken down to CO2 and H2O.

Ans-6 option (b) Glycolysis

Ans-7 Option (d)- Pentose phosphate pathway

Ans-8 Option (e) 2/2 (2ATP and 2 NADH)

Ans-9 Option (b)- catabolism
