1i Now that you have calculated the oxygen consumption per hour for this rat, you can calculate the metabolic rate per kilogram of body weight with the following equation (note that you need to convert the weight data from grams to kilograms to use this equation). Metabolic rate = (ml O2/hr)/(weight in kg) = ml 02/kg/hr Enter the metabolic rate in the field below and then select Submit Data to display your results in the Lab Report. ml O2/kg/hr

Following several days at high altitude the body responds to the decreased oxygen content of the atmosphere by increasing the amount of 2,3-bisphosphoglycerate it produces. Based on this information and refering to the graph below, identify the correct response from the options. Y (fraction saturation) 1.0 0.8 0.6 0.4 0.2 0.0 0 20 Oxygen Binding plot 40 60 p02 (torr) 80 100 A) Curve y=high altitude and gives a greater release of oxygen to the tissues B) Curve x = high altitude and gives a greater release of oxygen to the tissues C) Curve y=high altitude and allows more oxygen to be bound at low oxygen levels D) Curve x = high altitude and allows more oxygen to be bound at low levels

Which of the following are TRUE, regarding patterns of Oxygen Consumption in horses traveling at different speeds, based of the following data: A Walk o Trot • Gallop 100 - Gallop 16 12 Trot Walk 2 3 4 6 2 3 4 Running speed (ms-) Running speed (ms-) When horses trot, metabolic Cost of Transport is independent of speed. OAt the optimum speeds within each gate, metabolic Cost of Transport is independent of speed. These data show that Horses have specific adaptations for walking, trotting, and galloping. Metabolic Rate is constant, regardless of speed To travel a distance of 10 miles, it is most energetically efficient for a horse to walk. Metabolic Cost of Transport increases with increases in running speed. Rate of oxygen consumption (ml 02s) Millilitres of oxygen consumed to move

The kinetic data in the following table were obtained for the reaction of carbon dioxide and water to produce bicarbonate and hydrogen ion catalyzed by carbonic anhydrase. H2O + CO2--> HCO3 + H+ Carbon Dioxide Concentration (mmol L-') 1.25 2.5 5.0 20.0 1/Velocity (M'sec) 36 x 10³ 20 x 10³ 12 x 10³ 6 x 10³ [H. DeVoe and G. B. Kistiakowsky, J. Am. Chem. Soc. 1961 83 (2), 274-280.] Use Excel (or similar) to generate a Line Weaver-Burke plot, then use the equation for a linear-fitted trend line to calculate the substrate affinity of CO2 for carbonic anhydrase. Answer in units of mM. Enter numerical values only, no letters or symbols. Round answer to 2 significant figures.

The “mean-speed theorem” for finding average velocity under constant acceleration, proposed by the Oxford Calculators, and demonstrated geometrically by Nicole Oresme, is expressed algebraically as: density = weight/volume (m1)(v1) = (m2)(v2) (vm) = 1/2 (v0 + vf) s = (v0)(t) + 1/2 (a)(t2) velocity = distance/time
