ATP levels in fatigue is slightly less than ATP levels during rest. This indicates that mitochondrial function is normal in both cases. Fatiguing the muscles does not cause decrease in ATP levels.
Lactate levels are high after exercise. This is due to anaerobic glycolysis during exercise leading to rise in lactate levels.
Phosphocreatinine levels decrease after exercise because of increase glycolysis. Since there is limitation of oxygen supply to muscles during exercise there is faster depletion of PCr and acidosis
Creatinine levels are increased after exercise ..
2. (15 points) Look at the following graph, created from data published in "Effect of ambient tem...
1. According to the paper, what does lactate dehydrogenase (LDH) do and what does it allow to happen within the myofiber? (5 points) 2. According to the paper, what is the major disadvantage of relying on glycolysis during high-intensity exercise? (5 points) 3. Using Figure 1 in the paper, briefly describe the different sources of ATP production at 50% versus 90% AND explain whether you believe this depiction of ATP production applies to a Type IIX myofiber in a human....
