The net products of glycolysis in a muscle cell

The net products of glycolysis in a muscle cell are:$$(1\mathrm{pt}$$.)$$1\mathrm{NADH}$$2 ATP 2 lactates 2 pyruvates 7. The reactions of glycolysis occur in the cells; the reactions of the citric acid cycle occur in the (1.pt.) 8. When energy is released during catabolism, it is temporarily trapped in high-energy bonds of electrons of certain compounds. Which of the following is NOT associated with carrying potential energy? ( 1 pt) ATP FAD$$\mathrm{FADH}3$$NAD*$$\mathrm{NADH}$$Physical exercise results in skeletal muscle contraction, an active process that requires chemical energy in the form of ATP. Initially, small amounts of ATP are available within the skeletal muscle fibers.

The available ATP may sustain contractions for about 15 seconds before the ATP needs to be replenished. Cellular respiration is one mechanism by Which muscle fibers produce and replenish their ATP. Cellular respiration increases the avallability of ATP by consuming oxygen and glucose while producing water and carbon dioxide as a waste byproduct.

Thus, during exercise, as the metabolic activity of the muscle fibers increase, the concentration of oxygen in the muscle tissue decreases. Other byproducts of metabolic activity (temperature, acidity, and CO2 concentrations) likewise increase with metabolic activity. The increased presence of these metabolic byproducts is detected by specific homeostatic sensors that send out signals to the local vasculature and cause vasodilation, thereby shifting blood flow from less active tissues to the nearby exercising muscles.

The greater flow of blood into the exercising muscle resolves the oxygen loss while simultaneously removing the waste and other byproducts of the increased metabolic activity. (2 pts.) 9. Number the following 1.5 in the order in which the events occur: Blood deliver to the skeletal muscle increase in order to provide more oxygen. Skeletal muscle metabolism increases. You start to exercise. Oxygen sensors cause local blood vessels to dilate. Skeletal muscle oxygen demand increases:
