Which of the following would most greatly increase the activity of an enzyme functioning in the small intestine?
Correct answer: D. Increase the amount of enzymes
- A. Decrease the temperature
- B. Increase the amount of substrate
- C. Decrease the Ph
- D. Increase the amount of enzymes
Explanation
Increasing the amount of enzymes is the best way to increase enzyme activity is because enzymes are catalysts, and they work by binding to their substrate and then catalyzing a reaction. The more enzymes that are present, the more substrate molecules can be bound and catalyzed, which leads to an increase in the reaction rate.
