Document Summary

Bch210h lisa zhao 2012 | page 1. Lecture 28: glycogenolysis if pyruvate accumulates as a result of not enough blood (and thus o2) supplied to the muscle (bc out of shape), lactate will accumulate and drop ph, making it painful in muscle cramping. Nadh will also be converted to nad. Sy recovers and pulls lactate back into pyruvate. Nonathletes would lose lactate to the blood and recycled in the liver (but not favourable bc you would be losing this imp fuel) Sufficient o2 in mitochondria will allow pyruvate to be recovered from lactate (breathe heavily) Blood has limited reserve for glucose if glucose level drops, brain and other organs will be very sensitive to his. Needs a backup reliable source of fuel glycogen. Glycogen can be broken down (is available in muscle and liver) to serve as a source of nrg and blood glucose. Hormones reacting to exercise and level of blood sugar can effect glycogen breakdown mobilization.
