Consider a uniport system where a carrier protein transports an uncharged substance A across a cell membrane. Suppose that I a certain ratio of [A]inside to [A]outside, the AG for the transport of substance A from outside the cell to the inside, outside Ainside, is -10.3 kJ/mol at 25°C. That is the ratio of the concentration of substance A inside the cell to the concentration outside? Alinside AJoutside Choose the true statement about the transport of A under the conditions described. Because AG is negative, the ratio [A]inside/[A]outside must be greater than one. O Increasing [A]outside will cause AG for movement of Aoutside to Ainside to become a smaller negative number. Movement of Aoutside to Ainside will be spontaneous. O Decreasing the concentration of the uniport protein in the membrane will cause AG to become a larger negative number.

9.96 Most first aid "cold packs" are based on the endothermic dissolution of ammonium nitrate in water: NH4NO3(s)NH4+(aq)+NO3(aq) H= 25.69 kJ A particular cold pack contains 50.0 g of NH4NO3 and 125.0 g of water. When the pack is squeezed, the NH4NO3dissolves in the water. If the pack and its contents are initially at 24.0°C, what is the lowest temperature that this bag could reach? (Assume that the ammonium nitrate solution has a specific heat of 4.25J g-l K-l, and that the heat capacity of the bag itself is small enough to be neglected.)
Consider a metal ion A2+ and its nitrate salt, In an experiment, 35.00 mL of a 0.217 M solution of A(NO3)2 is made to react with 25.00 mL of 0.195 M NaOH. A precipitate, A(OH)2, forms. Along with the precipitation, the temperature increases from 24.8C to 28.2C. What is H for the precipitation of A(OH)2? The following assumptions can be made. â€¢ The density of the solution is 1.00 g/mL. â€¢ Volumes are additive. â€¢ The specific heat of the solution is 4.18 J/g C.
When 7.11 g NH4NO3 is added to 100 mL water, the temperature of the calorimeter contents decreases from 22.1 C to 17.1 C. Assuming that the mixture has the same specific heat as water and a mass of 107 g, calculate the heat q. Is the dissolution of ammonium nitrate exothermic or endothermic?
One researcher reported that they were ables to produce 8.4 molecules of H2 per glucose molecule fed to the cells. how large is this compared to the maximum theoretical yield assuming all of the NADPH and H+? For reference, suppose that hydrogen gas in a cell is synthesized using two protons and two electrons using enzymes.
The hydrolysis of ATP to form ADP requires energy to break the bonds initially, but releases moreenergy as bond are remade making the reaction exothermic overall. The Gibbs free energy for thisreaction is -30.5 kJ/mole, meaning that it is also exergonic (ΔG=-). This energy can be used by otherbiological systems if this reaction is coupled with another less favorable one. In this case, the creation ofglucose-6-phosphate, C6H10O9P, this is a pivotal intermediate in many biochemical pathways.
