Examine the diagram. Which of the following statements best describes how an enzyme functions like a lock and key?

• An enzyme slows down a cell's metabolism like a lock slows down a trespasser.

• The active site stays locked unless the products are nearby.

• The enzyme is like a key that unlocks a cell's ability to digest food.

• The substrate is like a key that has a shape that fits the lock, which is the active site of the enzyme.

Which of the following processes occurs in both aerobic respiration and anaerobic respiration?

• synthesis of acetyl CoA

• Krebs cycle

• glycolysis

• electron transport chain

The graph shows how the activity of an enzyme changes at different temperatures. Which statement best describes what happens to the enzyme when the temperature of the reaction increases to 63°C?

• The enzyme is used up and the reaction reverses.

• The enzyme begins to slightly decrease the rate of the reaction.

• The enzyme continues to increase the rate of the reaction.

• The enzyme changes shape and can no longer speed up the reaction.

What stage of cellular respiration produces the most ATP?

• citric acid cycle

• electron transport chain

• glycolysis

• Krebs cycle
