Question

Enzymes differ from inorganic catalysts in
A. Not being used up in chemical reactions
B. Working at high temperature
C. Being proteinaceous in nature
D. Working at high pH

Answer 1

Hint: Enzymes are protein molecules. It acts as a catalyst in a body cell. They speed up a chemical reaction. They have a wide range of functions in a body which are very important. They help in digestion, aiding, and metabolism.

Complete answer: Enzymes are highly specific. Enzymes are those molecules that catalyze biochemical reactions. These are biological polymers. Substrates are the molecules upon which enzymes may act, and the products are those in which the enzyme converts the substrates into different molecules. Metabolic pathways are dependent upon the enzymes for catalyzing the individual steps.
A catalyst is a chemical that without being changed by the reaction itself increases the rate of a chemical reaction. Within the homeostasis constraints of a living system, enzymes allow many chemical reactions to occur. Enzymes function as organic catalysts. A catalyst is a chemical involved in a chemical reaction.
Any organic compound that functions as a catalyst is known as an organocatalyst.
Organocatalysis refers to a type of catalysis in which the rate of a chemical reaction is increased by an organic catalyst which is called an organocatalyst, that consists of various elements such as carbon, hydrogen, sulfur, phosphorus, and other non metal elements found in organic compounds.
Their lack of sensitivity to moisture and oxygen, their availability, low cost, and low toxicity are some advantages of the organocatalysts.
Enzymes are proteinaceous in nature whereas inorganic catalysts are not.
So, the correct answer is “Option C”.

Note:
Enzymes catalyze a reaction which in presence of a catalyst proceeds the reaction faster. Inorganic catalysts promote a chemical reaction between many different reactants. Enzymes are proteinaceous in nature whereas inorganic catalysts are not proteinaceous in nature. Examples of inorganic catalysts in chemical reactions include: potassium permanganate - Hydrogen peroxide will decompose into water and oxygen gas.
