1. Enzymes

2. What is an enzyme?

3. Answer:
They are a protein that catalyze (speed up) the rate of chemical reactions.

4. What are the different parts of a chemical reaction?

5. Answer:
Reactants (substrates)
Products

6. What about enzymes makes the rate of the reaction increase?

7. Answer:
They have a specific shape that allows the substrates to fit perfectly together thus making the reaction happen quickly.
The proximity of the substrates allows chemical bonds to be created or broken easily.

8. What does the process of a chemical reaction look like with an enzyme?

9. Answer:

10. What is this method called?

11. Answer:
The lock and Key Method

12. What is the difference between a catalyst and an enzyme?

13. Answer:
Catalysts are a substance or chemical that speeds up any reaction. An enzyme is a catalyst inside the body.

14. What is the difference between an exothermic and endothermic reaction.

15. Answer:
Endothermic is when a reaction takes in energy while an exothermic reaction gives off energy.

16. Know how to read and understand a graph such as this:
Is this endo or exothermic?

17. Answer:
Exothermic

18. Is the following endo or exothermic?

19. Answer:
Exothermic

20. How much energy did it take for this reaction to occur?

21. Answer:
58kJ

22. How much energy was given off in the reaction?

23. Answer:
35 kJ

24. What would an enzyme to to the amount of energy needed for this reaction to occur?

25. Answer:
Take it from 58 kJ to something lower.

26. Is the following endo or exothermic?

27. Answer:
Endothermic

28. How much energy did it take for this reaction to occur?

29. Answer:
25kJ

30. How much energy was taken in during the reaction?

31. Answer:
15 kJ

32. What would an enzyme to to the amount of energy needed for this reaction to occur?

33. Answer:

34. How do you find the rate of the reaction?

35. Answer: Find the slope of the line.
Change in X / Change in Y = Slope/Rate
