Question

Why are enzymes necessary? to the rate of decomposition to act as a catalyst in chemical reactions to conserve the stored energy of a cell

Answer 1

Answer:

Option B, to act as a catalyst in chemical reactions

Explanation:

Enzymes are organic bio molecules that act as catalyst to increases the rate of a bio-chemical reaction involved in any biological process. All enzymes are made of amino acids and have suffix -ase at the end of their name.

For example -

Enzyme Amylase catalyses the chemical processes involved in the digestion of sugar in mouth. It increases the rate of conversion of  starch molecules into smaller glucose and maltose molecules.

Thus, option B is correct

Answer 2

Enzymes acts as a catalyst in chemical reactions to speed up the rate of reaction.

Enzymes are not necessarily needed because substrates can disintegrate on their own, but enzymes are helpful to aid this process.
