Enzyme Lab

-Get into groups

-Each group is going to preform a different lab

-Effect of temperature on enzymes

-Effect of pH on enzymes

-Effect of enzymes on starch

-Get into your group and read the whole lab sheet

-Make sure each member of your group knows what to do.

-Know all the steps before you begin a lab

-If you skip a step, apply the wrong step, or are not sure what you are doing you lose points

-You are more than welcome to ask questions before starting a step

Questions

1) What is a catalyst?

2) Why are enzymes said to exhibit specificity?

3) What would happen if you keep increasing the amount of substrate but keep the same concentration of enzymes?

4) Of the temperatures you tested, which showed the greatest activity? Why do you think that is?

5) Of the pH values you tested, which showed the greatest enzyme activity? Why do you think that is?

6) Why do you think it is bad for a human to have a really high fever?
