Question

explain why only small amount of enzyme is need to catalise reaction involving many molecules

Answer 1

Explanation:

Enzymes are biological catalysts which speed up chemical reactions in our body without being used up. Each enzyme corresponds to one specific substrate, and then breaks it down into simpler products. For example, pepsin will work only on proteins, and then break them down into amino acids.

In a reaction, a small presence of a catalyst is enough to lower down the activation energy of the reaction, so not much is needed to start the reaction.
