Lectures #8-10: Intermediary Metabolism Facts 1. What is ATP. What is its energy content? How is the G of ATP hydrolysis “ideally positioned” to act as both an energy receiver from metabolism, but an energy donor to many other reactions? 2. Give three examples of cellular activities powered by ATP. 3. What is meant by the phrase “ ATP homeostasis”? 4. Name the three primary energy systems in muscle that can generate ATP. What one factor determines which system(s) is/are utilized for energy during exercise? 5. True or False: Phosphagens and Anaerobic metabolic pathways can produce ATP at a faster rate than aerobic pathways. 6. What is a “phosphagen”? Describe the two pathways by which the body’s small, stored reserve of high- energy phosphate can rapidly replenish ATP levels in the short term (such as exercise onset). 7. If cellular energy use (exercise) is sustained at high levels for more than a few seconds, the reserves of phosphagens will be inadequate to maintain [ATP]; what is the body’s next metabolic line of defense? 6.
