Question

diagramming a catalyzed reaction: below is an enzyme that is responsible for a hydrolysis reaction. complete the diagram by drawing in the missing pieces described. draw a substrate that will fit the active site of the enzyme. draw the enzyme - substrate complex. draw two products being released by the enzyme. visualizing a graph: draw a generalized graph of the action of an enzyme as the temperature changes from 40°f to 110°f. mark the temperature of optimal enzyme activity at 80°f.

Explanation:

1. For the enzyme - substrate part: The substrate should have a shape complementary to the active - site of the enzyme (lock - and - key model). The enzyme - substrate complex is formed when the substrate binds to the active site. After the hydrolysis reaction, two products are released from the enzyme.
2. For the graph: Enzyme activity generally increases with temperature from 40°F to the optimal temperature of 80°F due to increased molecular motion and more frequent collisions between the enzyme and substrate. Beyond 80°F, the enzyme starts to denature, and its activity decreases.

Answer:

1. For drawing the substrate: Draw a shape that fits snugly into the 'V' - shaped active site of the enzyme.
2. For drawing the enzyme - substrate complex: Draw the substrate bound to the active site of the enzyme.
3. For drawing the products: Draw two separate shapes coming away from the enzyme.
4. For the graph: Draw a curve that starts at a low reaction rate at 40°F, increases steadily until it peaks at 80°F (optimal activity), and then decreases as the temperature rises from 80°F to 110°F. Mark 80°F on the x - axis at the peak of the curve.
