the membranes permeability to potassium ions‚ hence the membrane returns to Ek. Explanation of the (ionic) mechanisms underlying generation of the action potential leads directly to understanding impulse propagation. The main feature underlying the ion currents associated with the action potential is that both the sodium and potassium conductances are voltage dependent. Depolarisation increases the membrane’s conductance to sodium ions and‚ after a delay‚ potassium. Hence it becomes more likely

water‚ the above titration cannot be performed directly by a standard iodine solution because of the insignificant end point. Thus‚ alternative method‚ back titration‚ will be employed. Two equations are involved. First‚ standard potassium iodate(V) (KIO3)‚ potassium iodate(KI) and dilute sulphuric acis(H2SO4) react to find out the excess quantity of iodine. Below shows the equation. second Second‚ the iodine generated reacts with ascorbic acid immediately. While the excess iodine is the titrated

The concentrated solution is normally made as a 1 in 800 solution. You are asked to supply a patient with sufficient of this solution to allow them to make of use 25 mls of the further diluted solution (1 in 20) 3 times a day for 49 days.

knowing murder of his wife. In this case‚ the medical examiner considered a variety of different factors‚ with respect to time of death‚ including the concentration of vitreous potassium following the death of the defendant’s wife. Even though not an exact science‚ State v. Dreher (1997) stated that “the victim’s potassium concentration level was 7.3 milliequivalents per liter” which led to the estimation that the victim had died ten hours earlier‚ give or take four hours (1997‚ p. 34).

agar-water gel containing two wells. Pinch of potassium permanganate (KMnO4) and methylene blue (C16H18N3SCl) were simultaneously introduced to each dish and measured the distance and its rate. Methylene blue‚ having the largest molecular weight‚ displayed the smallest diameter 15.67 and diffused at the slowest rate (0.78mm/min). Next is potassium permanganate with a diameter of 13.33 mm and rate of diffusion of 2.54mm/min. The fastest is the potassium permanganate with 13.33 mm diameter and diffusion

magnesium depletion‚ create auxiliary potassium depletion. Magnesium hinders potassium‚ which then magnesium pushes the potassium out the cells through renal excretion causing hypokalemia. In order for the cell to keep up the typically high intracellular grouping of potassium the expansion in the membrane permeability to potassium as well as the restraint of Na+-K-ATPase needs to take place. 4.
