Question

enzyme structure

1. enzymes are a type of protein. like other proteins, they are made of small building blocks (monomers!) called
2. every enzyme has a different (order) of amino acids, so every enzyme has a different (shape).
3. what is the active site of an enzyme?
4. complete the analogy: enzyme is to as substrate is to

temperature and ph

1. what two things happen if an enzyme undergoes significant changes in temperature or ph?

1.
2.
review
enzymes are...

1. - they speed up chemical reactions
2. - they only catalyze specific reactions with specific substrates, like a lock and key.
3. - slight changes in ph or temperature can cause them to stop working.

Explanation:

1. Proteins are made of amino - acids.
2. Sequence determines shape.
3. Site where substrate binds.
4. Lock; key.
5. Denature; lose function.

Review: 1. Catalysts. 2. Specific. 3. Sensitive.

Answer:

1. Amino acids
2. Sequence; shape
3. The region of an enzyme where the substrate binds
4. Lock; key
5. 1. Denature 2. Lose catalytic function
