Discuss the relative effectiveness of dieting and exercise in losing weight noting that most athletic activities consume food energy at a rate of 400 to 500W while a single cup of yogurt can contain 1360KJ (325 kcal) specifically is it likely that exercise alone will be sufficient to lose weight? You may wish to consider that regular exercise may increase the metabolic rate, whereas protracted dieting may reduce it
The Nutrition Facts label on most food products shows % daily values based on a food energy requirement of 8,360 kJ (2,000 kcal) at normal resting state. a) Assuming that the efficiency of converting food energy to ATP is 50%, calculate the mass of ATP (in kg) that is harvested daily by the human body from 8,360 kJ of food energy. A total of 30.5 kJ of energy is needed to synthesize one mole of ATP under standard conditions. The molar mass of ATP is 505 g/mol. b) For an average 68-kg (150 lbs.) human adult, calculate the % mass of extracted ATP (from your answer in 2a) relative to body weight.
One food calorie = 1 X 103 calories = 1 kcal. A typical adult ingests about 2200 food calories per day. (A) show that an adult uses energy at about the same rate as a 100-W light bulb. {B) Calculate the total annual metabolic energy expenditure of the 6 X 109 people on the earth and compare it with the 4 X 1020 J per year energy used by the world economy. Assume all persons consume 2200 food calories per day, which is obviously incorrect.
According to Kleiber’s law, for the vast majority of animals, an animal’s metabolic rate is proportional to m 0.75, where m is the animal’s mass. When we plot the graph of the common logarithm of the mass on the horizontal axis and the common logarithm of the metabolic rate on the vertical axis, we get a straight line. Explain why the graph is a straight line. What is the slope of the line?
Which of the following metabolic processes can occur withouta net influx of energy from some other process?(A) ADP +~P i S ATP + H2O(B) C6H12O6 + 6 O2 S 6 CO2 + 6 H2O(C) 6 CO2 + 6 H2O S C6H12O6 + 6 O2(D) Amino acids S Protein
A 70-kg adult human (154 lb) could meet his orher entire energy needs for one day by eating 3 moles ofglucose (540 g). (We do not recommend this.) Each mol-ecule of glucose generates 30 molecules of ATP when it isoxidized to CO2. The concentration of ATP is maintained incells at about 2 mM, and a 70-kg adult has about 25 litersof intracellular fluid. Given that the ATP concentrationremains constant in cells, calculate how many times perday, on average, each ATP molecule in the body is hydro-lyzed and resynthesized.
Ouabain specifically inhibits the Na+K+ ATPase activity of animal tissues but is not known to inhibit any other enzyme. When ouabain is added to thin slices of living kidney tissue, it inhibits oxygen consumption by 66%. Why? What does this observation tell us about the use of respiratory energy bykidney tissue?
Which of the following statements correctly describe(s) the reaction: ADP + Pi + H+ → ATP + H2O ΔG°'= +7.29 kcalmolkcalmol A. ATP is less stable than ADP. B. Hydrolysis of ATP is spontaneous. C. Phosphorylation of ADP is nonspontaneous. D. Conversion of ATP to ADP will release heat.
A glucose molecule is split, converted to ATP (another chemical), which is then used for a runner's sprint. Heat is given off in the process. Describe the changes in energy types from the beginning of the sprint to the end. Would you consider this reaction endothermic?
Camels survive in the desert because they derive water from the large deposit of triglyceridesstored in their humps. How many net moles of water and ATP can be produced from the breakdown ofone mole of the triglyceride, tripalmitoylglycerol, to glycerol and CO2 ? [Don’t forget that ADP + Pi ATP + H2O
A 75 kg person doing light work requires about 3000 kcal of food energy perday, 40% of which is actually used by the body’s cells. (The other 60% is lostas heat and in waste products.) Before being used by the cells, effectively allof this energy is stored in ATP, which is then cleaved into ADP and PO3−2 , with the release of 12.5 kcal per mole of ATP.(a) How many moles of ATP are turned over per day in this fashion? Whatmass of ATP does this correspond to? (The molecular weight of ATP is507 g/mol.)(b) The body actually contains approximately 5 g ATP. Estimate the averagerecycle time for an ATP molecule. You see that it is much more efficientto reuse ADP rather than to synthesize it de novo (from scratch).
The respiratory quotient (RQ) is the ratio of the Liters of CO2 produced to the Liters of O2 consumed by an individual (CO2 exhaled in liters)/(O2 inhaled in liters). It is used as a measure of basal metabolic rate and can indicate which types of molecules are being used by a person to produce energy. For glucose (C6H12O6), this value is 1 as the equation for the complete oxidation of glucose is: C6H12O6 + 6 O2 → 6 CO2 + 6 H2O For fatty acids that are degraded through beta oxidation and fed into the TCA cycle, the RQ value would be ______ the values for glucose oxidation.
