What is the purpose  of an enzyme?

• give permission for the reaction
• raise activation energy
• speed up reactions
• control how many reactions occur

What happens when enzymes are heated to a high temperature?

• The enzymes die.

• The shapes of the enzyme are altered or denatured

• The enzymes' amino acid sequence changes.

• The enzymes remain the same

Which substrate would match this enzyme?

• 
• 
• 
• 

When an enzyme tightens around a substrate, this is called:

• An awkward hug

• Induced fit

• Competitive Inhibition

• Non competitive Inhibition

What's going on in this picture?

• The enzyme is taking the red substrate and turning it blue

• The enzyme's active site is blocked by a competitive inhibitor

• The enzyme can't function if too many substrates are trying to bind

• This is an example of an anabolic enzyme reaction
