Lesson on Enzymes

Enzymes

​What are enzymes?

Enzymes is a molecule that changes the rate of a chemical reaction.

Enzymes function​

​Enzymes speed up the chemical reactions in the body lowering the amount of energy needed.

​

​

​What are enzymes made of?

1. ​Proteins-composed of amino acid chains.

2. ​Substrate-the substance in which an enzyme acts on. 

3. ​Active Site- is where a substrate binds with the enzymes.

​Enzymes

​Coenzymes and cofactors assist enzymes to promote their chemical reactions.

​Enzymes

​Catalyst - increase the rate of the reactions. 

​What effects the enzyme?

• ​pH

• ​temperature

​​Enzyme Inhibitors

substances which alter the catalytic action which slows down or stop reactions
