Section 4: Enzyme Activity Lab (2 pts each question)
Directions
Go to the Enzyme Activity PowerPhys lab in WileyPLUS (you must be logged into the
classroom).
You will perform the lab and answer questions from this lab activity sheet as you move
forward through the experiment.
At the end of the lab there will be a lab report to fill out – you will not complete it
