Answer 14

Reversible

Question 15

Reactants are converted into products

Answer 15

Irreversible

Question 16

Proteins that catalyze by lowering activation energy

Answer 16

Enzymes

Question 17

Energy required to start a reaction

Answer 17

Activation energy

Question 18

Answer 18

Substrates

Question 19

Region in enzyme with a specific shape

Answer 19

Active Site

Question 20

What are the steps in facilitating reactions?

Answer 20

Substrates bind to active site, enzyme substrate complex forms, temporary shape change occurs, product leaves active site
