- 293What are the three major mechanisms by which exercise increases glycolytic rate?Using the set of data that follows, calculate how many of themolecules of O2 that were used in aerobic catabolism by JuliusCaesar are in each liter of atmospheric air today. All valuesgiven are expressed at Standard Conditions of Temperature andPressure (see Appendix C) and therefore can be legitimatelycompared. Average rate of O2 consumption of a human maleduring ordinary daily activities: 25 L/h. Number of years afterhis birth when Caesar was mortally stabbed near the RomanForum: 56 years. Number of liters of O2 per mole: 22.4 L/mol.Number of moles of O2 in Earth’s atmosphere: 3.7 × 1019 mol.Number of molecules per mole: 6 × 1023 molecules/mol. Amountof O2 per liter of air at sea level (20°C): 195 mL/L. Be prepared tobe surprised! Of course, criticize the calculations if you feel theydeserve criticism.

- What are the major energy stores of the body, that are used as substrates for fuel during exercise? Be specific.What is the estimated relative VO2 of someone walking on a flat treadmill at 2 mph and a 1% grade. How many metabolic equivalents (METs) is this equal to? Using the METs, identify whether the intensity of this activity would be classified as very light, light, moderate, or vigorous then explain why you believe this to be the case.
