Peptide bonds in proteins can be broken down by the enzyme peptidase. Adrian orders a hamburger and French fries for lunch. He adds cheese ad mayonnaise to his hamburger, and then sits down to eat lunch with his friends. Which structure would most likely result from the action of peptidase in Adrian's small intestine?

• Carbohydrates

Meat tenderizer contains an enzyme that interacts with meat. The normal temperature range that the enzyme can work is 21 degrees Celsius to 24 degrees Celcius. If the meat is coated with tenderizer then place in a refrigerator (range = 4C to 10C) for a short period of time, how would enzyme be affected?

• The enzyme would be less effective or may not work at all in the refrigerator temperature range.
• The enzyme would work better in the refrigerator temperature range.
• The enzyme would be completely destroyed in the refrigerator temperature range.
• The enzyme would have no effect on the meat in the refrigerator temperature range.
