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. Discuss how ATP is critically important to cellular chemical processes. Enzymes are protein materials that control chemical processes. Describe the specific mechanisms of enzyme function. 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. Make sure your explanation of enzymes is informed by the textbook.
