Best explains how enzymes speed up chemical reactions?

Answer 1

Enzymes speed up the chemical reactions by forcing the reactant molecules into their correct orientation. The enzymes also lower the required energy for collision to produce a reaction.

Answer 2

Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur. They do this by bringing the reacting molecules closer together and providing an alternative pathway for the reaction to follow. This allows the reaction to proceed more quickly and efficiently than it would without the enzyme.
