If 35 % of the body mass of this 96 kg adult consists of TGs (in adipose tissue), what is the total available fuel reserve, in kJ and kcal, in the form of TGs? Assume energy value of TGs = 37.4 kJ/g 1 kJ = 0.239 kcal

After infection, some T cells (a particular type of immune cell) may persist as memory T cells (TMcells). When they re-encounter the same pathogen, T­M­ cells rapidly divide to produce more T cells to help fight off the infection. This rapid cell division requires substantial energy. One way that this energy is provided to TMcells is via increased activity of the ETC. One standard type of experiment for analyzing oxidative metabolism is measuring the oxygen consumption rate OCR in the presence of different compounds. The lines indicate the time at which the different ETC/OxPhos inhibitors were added. Note that the inhibitors are never removed. Complete the table below. Time Period 1 2 3 4 Inhibitor added None Oligomycin (inhibits ATP Synthase) FCCP (Uncoupler) Rotenone + Antimycin (Complexes I and III) Can electrons flow? If so, from which compound to which compound? If not, what is preventing it?         Can H+move through the membrane? If so,…

The thermoneutral zone is the range of body temperatures over which an animal can maintain a constant basal metabolic rate. Which of the following patterns about thermoregulation is true?       A. Below the lower critical threshold, animals must decrease their metabolic rate in order to maintain body temperature    B. Animals living in the arctic have higher critical temperatures than do animals in the tropics    C. When outside temperatures are below the lower critical temperature for an animal, animals in the arctic increase their metabolic rate faster than do animals in the tropics    D. All of the above    E. None of the above

In the three different energy systems, name the energy compounds, and which systems are stressed during exercise of different intensities

Show sequentially, the total ATP Yield and the net ATP Yield in the complete oxidation of Glucose (from Glycolysis to Oxidative Phosphorylation) in the Muscle and Heart Tissues of a man. Indicate the differences in the ATP yield in both tissues.

explain the relationship between glycogen metabolism,  the pentose phosphate shunt, dyslipidemia, increased adiposity, statins, and sugar consumption

In absolute terms, fat oxidation _____ as exercise intensity increases from low to moderate levels, although the percentage contribution of fat may actually ______. Group of answer choices pick one only increases; increase increases; decrease decreases; increase decreases; decrease

(A) how much energy is necessary to heat 7.0 kg of water from room temperature (20 degrees Celsius) to its boiling point? (Assume no energy loss) (b) if electrical energy were used, how much would this cost at 45 cent per kWh?

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.

Excess Kcalories (Calories) will be stored as triglyceride in the adipocytes.  Which energy source has the lowest metabolic cost associated with this storage? Question 90 options: a)  Carbohydrate b)  Protein c)  Fat d)  Water
