(Topic of discussion

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.)


In this week discussion our main focus is the importance of the ATP and Enzymes. The ATP (adenosine triphosphate) has been called the energy currency of the cell. The ATP consists of an organic molecule called adenosine plus a tail of three phosphate groups. The triphosphate tail is the business end of the ATP which provide energy for the cellular work. Cellular work spends ATP, which is recycled when ADP and phosphate are combined using energy released by cellular respiration. The energy from processes that yield energy, such as the breakdown of the organic fuels, is transferred processes that consume energy, such as muscle contraction and other cellular work. The ATP run at a really fast pace up to 10 million ATP’s are consumed and recycled each second in a working muscle cell. Enzymes are proteins that speed up the chemical reactions without being consumed by those reactions. All living cells contain thousands of enzymes however, each one develop a separate chemical reaction. Proteins embedded in the plasma membrane perform a wide variety of functions, including regulating transport, anchoring to other cells or substances, promoting enzymatic reactions, and recognizing other cells.
