Question 1

ATP (adenosine triphosphate) has been called the energy currency of the cell. Briefly outline the cycle by which energy is stored in and released from ATP. Explain the importance of the phosphate bond to this series of processes. Be prepared to discuss how ATP is critically important to cellular chemical processes.

Question 2

Enzyme action and their importance to life

Enzymes are protein materials that serve to control chemical processes within the cell. Briefly describe how enzymes work and explain their importance to the chemical processes of living organisms. Pick a specific enzyme and describe its function and the importance of that function to life. Discuss how the loss of that enzyme would disrupt living processes? Be prepared to discuss the action and importance of the variety of enzymes used as examples in this discussion.
