Question

questions & conclusion

1. based on your observations, what is the substrate for the enzyme catalase?
2. why did the reaction with water and yeast not produce any foam?
3. what temperature did the enzyme work best? what happened to the enzyme in the hot water environment?
4. how did the acidic solution affect the enzymes activity?
5. how did the basic solutions affect the enzymes activity?
6. why is it important for an enzyme to have a specific shape?

Explanation:

1. Catalase acts on hydrogen - peroxide.
2. Water is not a substrate for yeast enzymes.
3. Enzymes have optimal temps; high heat denatures.

4 - 5. Acids/bases can alter enzyme activity.

1. Specific shape for substrate binding.

Answer:

1. Hydrogen - peroxide
2. Water is not a substrate.
3. Optimal temp exists; high heat denatures.
4. Can alter activity.
5. Can alter activity.
6. For substrate binding.
