Question

Who can answer these 10 questions for Biology? Need some help..it's about Enzymes.

1.) How does the small amount of enzymes affect the reaction rate? As the numbers of enzymes increase the reaction rate ____?

2.) How does the amount of substrate affect the reaction rate? As the amount of substrate increases the reaction rate ___?

3.) How does a change in temp. from 25 deg. to 50 deg. affect the rate of reaction rate?

Answer choices for 1-3
A.) goes up and down at random
B.) remains the same
C.) increases
D.) decreases

4.) What happened when the temp. was set to 75 deg?

5.) How does a change in temp. from 25 deg. to 5 deg. affect the rate of reaction rate?

6.) When the temp. was set at 0 deg. , the reaction rate?

Answer choices for 4-6
A.) The reaction increased due to molecules moving faster
B.) The reaction decreased due to enzyme moving faster
C.) Reaction rate stopped due to active site of enzyme denatured
D.) Reaction rate stopped due to substrate dissolving at high temp.
