Enzyme Checkpoint Review

Enzymes are a catalyst. What does that mean?

• Starts chemical reactions

• Stops chemical reactions

• Speed up chemical reactions

• Slow down chemical reactions

What is the function of an enzyme?

• Lower activation energy and speed up reactions

• Raise activation energy and speed of reactions are the same

• Lower activation energy and and slow down reactions

• Raise activation energy and speed up reactions

Which macromolecule is an enzyme?

• Carbohydrate

• Lipid

• Protein

• Nucleic Acids

What are the products in a reaction?

• The catalyst gets broken down

• The substrates join together

• The enzyme gets broken down

• The substrate gets broken down

What happens when an enzyme becomes denatured?

• The substrate changes

• The active site changes

• The products change

• Nothing changes

What causes an enzyme to become denatured

• Hot temperatures and strong pH

• Cold temperatures

• Weak pH

• Low temperatures and weak pH

What would have impacted the enzyme for apple juice production during our lab the most? If the enzyme...

• Was mixed with different types of applesauce

• Was mixed with off brand applesauce

• Was mixed with water from Lake Lanier

• Was warm

True or False: An enzyme will still function outside of its ideal pH conditions.

• True

• False

How are enzymes helpful for digestion?

• They build the substrates so that the body cannot break them down

• They break down food into smaller parts for the body to break down

• Enzymes don't help with digestion

When an enzyme becomes denatured, what is effected?

• Substrate

• Enzyme

• Active Site

• Enzyme-Substrate Complex
