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
