Enzyme vs. Substrate Substrate is the substance the enzyme

acts on during a chemical reaction.

Enzymes can be reused! They are not changed during a reaction.

Lock and Key

Enzymes are specific to the substrate. The shape of the enzyme determines the function of the enzyme.

How it works

Page 10: What are enzymes?? Enzymes are proteins. Enzymes speed up chemical reactions. Biological Catalyst pH, temperature, and substrate concentration.

Active Site The part of the

enzyme that binds to the substrate.

Page 11: What are enzymes?? Enzymes are proteins. Enzymes speed up chemical reactions. Biological Catalyst pH, temperature, and substrate concentration.

Temperature pH Concentration

Three Factors that Affect Enzyme Activity

Page 12: What are enzymes?? Enzymes are proteins. Enzymes speed up chemical reactions. Biological Catalyst pH, temperature, and substrate concentration.

• If too hot, enzymes will be denatured lose its shape and the active site will be destroyed

• It will not be able to bind with its substrate• Too low (cold), enzymes

will slow down

Temperature

Page 13: What are enzymes?? Enzymes are proteins. Enzymes speed up chemical reactions. Biological Catalyst pH, temperature, and substrate concentration.

pH Enzymes work best within a certain

range of pH values (Optimal) or they will be denatured
