activation energy

2

protein that catalyzes chemical reactions

enzymes

3

enzymes are made of

protein

4

how do enzymes speed up chemical reactions

by lowering the amount of activation energy needed to start the reactions

5

what is a benefit of lowering the activation energy needed to start chemical reactions

it leaves more energy available to complete the reaction

6

two ways a catalyst affects a chemical reaction

1. lowers activation energy 2. makes the reaction happen quicker
