Enzymes: Life's Catalysts — Homework
Review how enzymes lower activation energy before answering.
- 1.What happens to an enzyme itself after it catalyzes a reaction: is it consumed, or can it be reused?
- 2.Explain what activation energy is and what an enzyme does to it.
- 3.A catalase sample is boiled and then tested with hydrogen peroxide, producing almost no bubbling. Explain why, using the word "denature."
- 4.Explain why pepsin (a stomach enzyme) and trypsin (an intestinal enzyme) have very different optimum pH levels.
- 5.Describe the catalase-and-hydrogen-peroxide lab from this week and explain what the amount of bubbling in a given sample tells you about enzyme activity.
