How does alcohol affect IPSP and Potassium? Why do the ions move? Solution ANS: Entire body system is effected by alcohol consumption. alcohol is taken placed by every cell in organs by through the blood and it results electrolytes imbalance. So potassium levels of the body fluids is affected by electrically conductive ions. The altered body fluid ionic concentration causes ionic imbalances. Functions of Potassium: The nerves function, muscle contraction, hormonal balance and water balance is mainly based on Potassium levels. The imbalance between sodium and potassium ions causes hypertension. It effects ADH hormone levels. The body dehydration is normally prevented by Anti-Diuretic Hormone. After alcohol consumption alcohol suppresses ADH, upset the water balance and potassium ion concentration in cells. IPSP (Inhibitory postsynaptic potential): It is a postsynaptic potential that hyperpolarized and inhibits the responses. it decrease action potentials by moving membrane potential farther from threshold. It is generally results from opening of Potassium or chloride channels. Ions movement after alcohol consumption: The potassium ion move through the membrane more easily than sodium. The ions of the potassium is moved faster than sodium. Serum potassium levels were significantly lower in alcoholic patients. Ionic effect by Beer: The water content in beer is high and the soluble nutrients concentration is low. Beer alcoholic percent impairs normal ADH effected and the water content of beer is retained in body, so its results over fluid load in blood stream. The ion concentration of potassium is decreased and causes hormonal imbalance and thirst. Ions effect by Hard liquor: In Hard liquor the water concentration is low, so less water enters into body. Then the ADH is suppressed by alcohol, and the kidney process high amount of water from blood stream into urine. it leads to raise of potassium ion concentration in blood..
