The Venus flytrap is a plant that uses specialized leaves in order to capture and digest small insects.
Enzymes secreted by cells in the leaves of the Venus flytrap can digest*
Photosynthesis and respiration are alike in that they both*
Which statement is most likely correct regarding soil bacteria that inhabit the polar regions of Earth?*
In living cells, chemical processes, such as synthesis, all require the action of*
Many disorders are due to the inability of an individual to break down a particular chemical. Sometimes these disorders can be treated by giving the affected individual the appropriate*
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*
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 diagram below represents a model of a biological process that occurs in humans at normal body temperature, 37°C.
Increasing body temperature to 40°C would interfere most directly with the rate of function of structure*
Which statement explains the importance of maintaining a constant internal environment to ensure proper enzyme functioning?*
The graph below represents the effect of pH on three different enzymes at normal body temperature.
The graph illustrates that enzymes 1, 2, and 3*
In the diagram below, X represents a process that causes a protein to unfold and stop functioning.
Process X is most likely caused by*
Base your answers to questions 12 on the diagram below and on your knowledge of biology. The diagram illustrates the steps in a process that occurs in the cells of many organisms.
Based on the diagram, the process of glycolysis most likely*
Base your answers to questions 13 on the diagram below and on your knowledge of biology. The diagram represents a human enzyme.
Describe one role of enzymes in the human body. *
An accident resulted in a man’s hand being cut off from his arm. Paramedics arriving first on the scene placed the cut-off hand in ice. The man and his hand were flown to a hospital, where doctors successfully reattached the hand to his arm. Explain, using one biological reason, why placing the hand in ice improved the chances of saving it. *
Base your answers to questions 15 on the information below and on your knowledge of biology.
An enzyme was isolated from digestive juices taken from the small intestine. An experiment was set up to test the ability of the enzyme to break down protein. Two test tubes, labeled A and B, were placed in a hot water bath at 37°C, human body temperature.
Test tube A contained only protein and test tube B contained protein and the enzyme. The chart below shows the set-up.
After two hours, the contents of both test tubes were analyzed. Test tube A showed only the presence of protein. Test tube B showed the presence of the end products of protein digestion, indicating the enzyme had successfully broken down the protein.
Explain the importance of temperature in the functioning of enzymes. *
