Question

An enzyme which brings about change inside a group without altering the composition is
A. Isomerase
B. Epimerase
C. Mutase
D. Esterase

Answer 1

Hint: They are a class of isomerase that facilitate and catalyse group transfers within the same molecule. Enzymes are special proteins that speed up the rate of chemical reactions and act as biological catalysts in biological processes.

Complete Answer:
A catalyst is a substance that speeds up the activation energy required for chemical reactions. Most enzymes are specific to one reaction. The enzyme is not used up by the chemical reaction.

Isomerases belong to a family of enzymes that catalyse reactions involving the structural rearrangement of a molecule.These enzymes transform a molecule from one isomer to another, which means that the substance has the same molecular formula, but it has a different spatial structure.

Epimerase is an isomerase enzyme. They configure a symmetrical carbon atom from a substrate that has more than one centre for asymmetry and shapes interconverting epimers. Hydrolases are enzymes that use water to break up a chemical bond, which usually results in the separation of a larger molecule into smaller molecules. Esterase is a hydrolase enzyme that catalyses the hydrolysis of ester bonds in short-chain acyl groups of fatty acid esters.

Mutase is an enzyme that belongs to the class of isomerase. This family of enzymes is responsible for accelerating the transfer of a functional group from one part of a molecule to another.

Thus, the correct answer is option ‘C’ i.e., Mutase

Note:Enzymes have an impact on a variety of biological processes. Metabolic enzymes catalyse and regulate each biochemical reaction within the human body, making it necessary for cellular function and overall health.
