Glycolysis time frame during exercise
WebQuestion 9. Muscle lactate production increases when: a) oxygen is readily available. b) pyruvate cannot be formed from glucose breakdown. c) the pH of the muscle falls. d) glycolysis is activated at the onset of exercise. e) muscle glycogen becomes depleted. WebEric H. Awtry MD, Gary J. Balady MD, in Cardiology Secrets (Third Edition), 2010 6 How is exercise intensity defined?. Exercise intensity is defined by the amount of energy required for the performance of the physical activity per unit of time. This can be measured directly using respiratory gas analysis to quantify oxygen uptake during exercise or can …

WebSteps of aerobic glycolysis: Initially stored glycogen is converted to glucose. Glucose is then broken down by a series of enzymes. 2 ATP are used to fuel glycolysis and 4 are created so the body gains 2 ATP to use for muscular contraction. Pyruvate is created as the end product of the breakdown of glucose.
