Amylase
Lipase
Dinitrogenase
Succinic dehydrogenase
Melonate inhibits the growth of pathogenic bacteria by inhibiting the activity of Succinic dehydrogenase.
Succinic dehydrogenase, also known as succinate dehydrogenase or succinate-coenzyme Q reductase, is an enzyme involved in the electron transport chain and the tricarboxylic acid (TCA) cycle in bacteria. It catalyzes the conversion of succinate to fumarate, playing a crucial role in energy production.
Melonate is a competitive inhibitor of succinic dehydrogenase. It structurally resembles succinate and competes with it for binding to the active site of the enzyme. By binding to and inhibiting succinic dehydrogenase, melonate disrupts the normal functioning of the TCA cycle and electron transport chain, leading to a decrease in ATP production and inhibiting the growth of pathogenic bacteria.
Therefore, the correct option is (D): Succinic dehydrogenase

Given below are two statements:
Statement I: Low temperature preserves the enzyme in a temporarily inactive state whereas high temperature destroys enzymatic activity because proteins are denatured by heat.
Statement II: When the inhibitor closely resembles the substrate in its molecular structure and inhibits the activity of the enzyme, it is known as competitive inhibitor.
In the light of the above statements, choose the correct answer from the options given below:
Given below are two statements:
Statement I: In prokaryotes, the positively charged DNA is held with some negatively charged proteins in a region called nucleoid.
Statement II: In eukaryotes, the negatively charged DNA is wrapped around the positively charged histone octamer to form nucleosome.

Biomolecules are the most essential organic molecules, which are involved in the maintenance and metabolic processes of living organisms. These non-living molecules are the actual foot-soldiers of the battle of sustenance of life.
There are four major classes of Biomolecules – Carbohydrates, Proteins, Nucleic acids and Lipids.
