Question

Only a little quantity of which of these can influence the rate of chemical reaction

• A. Hormone
• B. Enzyme
• C. Alkaloids
• D. None of the above

Answer 1

The correct option is B Enzyme

Enzymes are proteins which accelerate the rate of the reaction. The substrate and product have different energy state. The energy gap between the substrate and the product is known as activation energy which is the minimum energy required to initiate a reaction. The enzymes lower the activation energy and lead to the faster conversion of substrate to the product. It accelerates the biochemical reaction so it is also known as a biocatalyst. Whereas, alkaloids do not influence the chemical reaction and small amount of hormones causes deficiency disorders.

So, the correct answer is option B.
