Enzyme Foldable Instructions: This information will all come from your careful reading of
Ch. 2.4 - Chemical Reactions and Enzymes.
Step 1: Use the foldable pattern below to create a four-tab, shutter fold as shown.
Step 2: On the very top edge of the foldable, title your
work as:
“FOUR STEPS IN ENZYME ACTIVITY – JOINING
SUSTRATES”
Step 3: On the FRONT of each tab, draw and color
the 4 general steps of enzyme activity using the sketch
below. Color the enzyme RED in every step. Color
substrate A YELLOW, substrate B BLUE, and the end
product GREEN.

Step 4: On the INSIDE of each tab, look up and list the following:
a. Tab 1 – Meaning of the words REACTANTS, ENZYMES, SUBSTRATE, & ACTIVE SITE.
b. Tab 2 – Explanation of “ENZYME-SUBSTRATE COMPLEX/LOCK & KEY FIT.”
c. Tab 3 – Definition of the word CATALYST and meaning of BIOLOGICAL CATALYST.
d. Tab 4 – Meaning of the word PRODUCTS, 3-4 examples of biological enzymes that are
useful in our cells AND the process they catalyze, and 3 things that can affect or regulate
enzyme function or activity.
Step 5: On the BACK of the foldable, define CHEMICAL REACTION and ACTIVATION ENERGY.
Include a copy of Figure 2-20 with your definition of activation energy.
