There Must be a sort of biological catalyst in order to react the raw materials together. what is the substance?

Enzyme

Explanation:

Enzymes are globular proteins that act as biological catalysts for various biochemical processes. they are involved in all biochemical reactions in our body.

Every chemical reaction requires activation energy i. e. the amount of energy needed to start a reaction between the reactants. Enzymes work by lowering this activation energy so that the reaction rate increases and the substrate is rapidly turned into the product.
