Explain your choice.Muscle Contraction In an experiment, the strength of a neural stimulus and the resulting muscle contraction are compared. A single motor neuron that synapses with one muscle fiber is observed in this experiment. One end of the muscle fiber is attached to a mass.

- The ion flows across neuronal membranes at rest and duringan action potential do not significantly change bulk ionconcentrations, except for that of Ca2+ ions. Resting Ca2+ ionconcentrations in cells are usually about 10–7 M, and Ca2+ ionsexert physiological effects at concentrations of perhaps 10–5 M.Explain why relative changes of intracellular [Ca2+] are muchgreater than for, say, [Na+] (12–50 mM).Calculate the free energy of transport for the movement of potassium by the sodium/potassium pump under normal physiological conditions: 4 mM serum potassium, 135 mM intracellular potassium, 37.1 °C, and resting potential -82 mV. Express your answer in kJ/mol. Show all work. Calculate the free energy of transport for the movement of potassium by the sodium/potassium pump under disturbed conditions of 2 mM serum potassium. Assume all other parameters remain the same. Express your answer in kJ/mol. Show all work. What factors could limit the continued action of the sodium/potassium pump when only 2 mM potassium is present in the blood plasma? Note that under normal physiological conditions, the cell interior contains 11 mM sodium and the blood contains 140 mM sodium.What happens to membrane potential during manipulation 4 in the attached figure (Figure 4.13 of the textbook)? 1 Efflux of Nat Nat efflux (logarithmic scale) 0 3 Recovery when K+ is restored 2 Nat efflux reduced by removal of external K 50 100 4 Efflux decreased by metabolic inhibitors, such as dinitrophenol, which block ATP synthesis 150 Time (min) 200 5 Recovery when ATP is restored " I 250 TATI 122 O Membrane potential does not change, because the Na+-K+ ATPase does not contribute to membrane potential. O Membrane potential is hyperpolarized, because the Na+-K+ ATPase is electrogenic and hyperpolarizes membrane potential when it is active. O Membrane potential is depolarized, because the Na+-K+ ATPase is electrogenic and hyperpolarizes membrane potential when it is active. 300
- The patient's muscle weakness, dizziness, and nausea are all due to hypokalemia. How does hypokalemia lead to muscle weakness? O hypokalemia leads to hypopolarization which results in fewer action potentials arriving at skeletal muscles O hypokalemia leads to hyperpolarization which results in fewer action potentials arriving at skeletal muscles O hypokalemia leads to hypopolarization which leads to too many action potentials arriving at skeletal muscles O hypokalemia leads to hyperpolarization which results in too many action potentials arriving at skeletal musclesAt the peak of the action potential, Vm is approximately -65 mV. Assuming normal intracellular and extracellular K+ concentrations (refer to the table), (1) calculate the driving force (in mV) that acts on K+ ions and (2) use the information obtained in part 1 to determine the direction in which K+ ions will flow (i.e., into the cell or out of cell)Activation of which pathway leads to a disinhibition of the thalamus and increased cortical activation?
