Enzymes help to

• speed up chemical reactions
• stop chemical reacations
• slow down chemical reactions

The active site is found on the

• substrate
• enzyme
• product

The substrate attaches to the

• active site on the enzyme
• active site on the product
• active site on the substrate

If you increase the temperature of an enyzme, you will

• increase the rate the enzyme works
• decrease the rate the enzyme works
• have not impact on how fast the enzyme works

A reaction will take place ________ with an enzyme than without.

• faster
• slower
• at the same speed

An inhibitor

• slows down or stops an enzyme
• speeds up an enzyme
• does nothing to an enzyme

Enzymes are a type of

• protein
• carbohydrate
• lipid
• macromolecule

Activation Energy is the energy

• needed to stop a reaction from taking place
• needed to start a reaction
• needed for an enzyme to create
• needed for a product to absorb

The product is formed from the

• substrate
• other products

Enzymes remain

• unchanged during the reaction
• unchanged at first and then change to match the products
• unchanged until the reaction has taken place and then they are killed
