Biological catalysts that are proteins are called enzymes. Enzymes bring the substrates together to form the enzyme-substrate complex, which leads to the generation of t â¦ he products of the reaction. 14 people found this useful. Jonathan Givens. 1 Contribution.
1 Catalysts â A catalyst is a substance that changes the rate of a chemical reaction, but is chemically unchanged at the end of the reaction. 2  An inhibitor does the opposite â it slows down chemical reactions.n this process, a catalyst first combines with a chemical to make a new compound. This new compound is unstable, so it breaks down, releasing another new compound and leaving the catalyst in its original form. Many enzymes (special biological catalysts) work in this way.
