Shrimp that live in the cold waters off Alaska will die if introduced into warm water. One likely reason these shrimp do not survive is that enzymes in the shrimp

• start to replicate

• change shape

• are composed of fat molecules that melt

• break down into small starch molecules

The Venus flytrap is a Plant that has a unique system by which it traps and breaks down its prey. Unsuspecting insects land on the leaf and touch tiny hairs located on the leaf triggering the leaf to close around the prey.

The substance responsible for breaking down the Venus flytrap's prey most likely contains

• chlorophyll molecules

• glucose molecules

• hormone molecules

• enzyme molecules

Students did an experiment comparing the

activity of four different enzymes, A, B, C, and D.

The results are represented in the graph below.

A valid conclusion based on the information in the graph is that

• the pH of some enzymes changes as the temperature changes

• enzymes change color in proportion to the rate of activity

• a difference in the pH of an environment changes enzyme activity

• enzyme activity causes acids to change into bases over time
