34. During moderate levels of activity - What happens to glycogen? - What does glucose become - what is its "fate?" - What do we call this process? - What are the mitochondria using to produce ATP? - Does glucose go directly into the mitochondria or is it cut (cleaved) into small parts? - How many ATP are coming from glycolysis (glucose to pyruvic acid) directly - How many ATP come from pyruvic acid being used by the mitochondria? - What are the different ways to make ATP during this level of activity? 35. During "peak" physical activity which metabolic pathway is our primary source of ATP production? - Did you keep in mind the number of ATP generated and what was the fuel source for this? - What substance is not being used efficiently by the mitochondria? - Why is this happening - What happens to this substance that is building up in the muscle cell? - How has the pH of the muscle changed? - Why is this not a good change? - Are you still using CP as a source of some ATP? - What are the different ways to make ATP during this level of activity? 36. Explain the Cori Cycle. - What organs/cells are involved? - Why is this not a very efficient pathway? 37. What are the two different metabolic pathways for pyruvic acid? 38. Define gluconeogenesis and what are examples of this process?
During a 1500-meter (i.e., 3-4 minute long) running race, which two metabolic pathways will be primarily involved? Group of answer choices ATP-PCr, anaerobic glycolysis ATP-PCr, oxidative phosphorylation Anaerobic glycolysis, oxidative phosphorylation All three pathways will contribute significantly
