Potassium

The sodium-potassium pumps is a plasma membrane transport protein and serve to push an ion into a cell against its concentration gradient. This type of action is known as active transport because it needs the energy to be able to move the ions against their concentration gradient. Generally, the solutes being pushed in or out of a cell will go from a low concentration gradient to a high concentration gradient. The sodium-potassium pump is crucial to kidney function, nerve signaling, and heart…

Activity #1 1. Potassium and Sodium. Potassium is more concentrated inside the cell and sodium is more concentrated outside the cell. 2. Resting membrane potential is the difference in voltage of the fluids inside a cell and outside a cell. It is measured by the difference in voltage inside and outside of the cell. 3. On the outside of the resting membrane potential it would remain at 0, however on the inside it dropped the voltage from -70 to -40. This happened because with the increase of K+,…

Potassium is everywhere. It races through the bloodstream, drifts in the air, swims through the water, and rises up roots of plants. Furthermore, it is vital for life to exist on earth, from the grass lions, bears, and humans trample on every day, to the fish and plankton in the ocean. Without potassium, the ninetieth element on the periodic table with chemical symbol “K,” life would be immensely different today, notwithstanding any in the first place. Potassium functions a significant role in…

Meta description: Potassium phosphate is a supplement that is used to treat or prevent hypophosphatemia. Potassium phosphate is an injection supplement used as a preventative in order to remedy low phosphorus in the blood. Overview Potassium phosphate is an intravenous injection used to prevent or treat hypophosphatemia, low phosphorus in the blood, through the use of a concentrated solution mixture of monobasic and dibasic potassium. Phosphorus occurs naturally in every cell in the body and…

INTRODUCTION: Losartan Potassium (LSP)[FIG.1.A], 2-n-butyl-4-chloro-1-[p-(o-1Htetrazol- 5-ylphenyl) benzyl]-imidazole-5 methanol monopotassium salt is a highly selective, orally active, non-peptide angiotensin II receptor antagonist indicated for the treatment of hypertension. It has a more potent active metabolite (II, 2-n-butyl-4-chloro-1-[2- (1H-tetrazol-5 yl) biphenyl- 4-yl) methyl] imidazole-5- carboxyl acid)[1]. The determination of Losartan has been carried out in tablets by HPLC,…

the human body. Potassium is very important electrolyte in our bodies; it helps with cell development and also plays a role in the electrical system of our body. A major organ affected by potassium is the heart. Potassium helps regulate our heart rate and rhythm. Too much or too little could cause an arrhythmia which is an abnormal heart rhythm. According to the Mayo Clinic, a normal range for potassium is between 3.6 and 5.2 millimoles per liter of blood. Having too much potassium in the blood…

In order to determine the extent to which the reversal potential for potassium determines the resting membrane potential of a given cell, a mechanism is needed to determine the change in membrane voltage across the cell in different extracellular potassium solutions. The intracellular recording technique consists of puncturing a prepared cell with a conductive pipette. The difference in potential between the extracellular electrode and the wire in the pipette is recorded and displayed on the…

solubility curve for potassium nitrate in water by measuring saturation temperatures for six different solution concentrations. We form a group of four and were assigned to work on series one while the other group work on series two. Throughout the lab, we set a hot bath water temperature at 85 degree celsius which affected how potassium nitrate dissolves in water and changed the saturation temperature. In addition, our group discovered that the mass of test tubes plus potassium nitrate relates…

solid compounds was supported with this experiment. The hypothesis stated that potassium hydroxide would have the greatest effect on the acidic solution. This was supported here as it had the highest average change in pH by far. On average, the pH value of the acidic solution increased by 12.5. This is significantly higher than the increase of the other solutions, which only increased around a pH of 4. The reason why potassium hydroxide seemed to be the strongest alkaline-forming substance is…

How gunpowder changed warfare How gunpowder was invented is that some scientists in china were experimenting Saltpeter a powerful agent potassium nitrate. It was used in medical compounds for years until a man thought about mixing the potassium agent with sulfur and charcoal, it had a result of a mysterious powder. Some observers said that smoke and fire the scientist’s body parts were burnt and the houses that they were working at burnt down too. The powder was used by the reigning Sung…
