Learning fascinating stuff. Each time there is an action potential, the concentration gradient of ions is disturbed, ie; the sodium ions diffuse in and potassium diffuses out (which is not really good if you want to maintain the ‘normal’ concentration gradients of these ions across the membrane and the normal resting potential). Hence, after eachContinue reading “Learning fascinating stuff 04”

Learning fascinating stuff.  Potassium channels are ‘selectively permeable’ to only potassium because they actually have a filter (carbonyl oxygens) on their outer surface that dehydrates ions. Only dehydrated ions can pass through the channel protein. Since, sodium ions are smaller than potassium ions, and the filter has a fixed width which fits just for potassium,Continue reading “Learning fascinating stuff 03”

Vitamin K injection is given to patients with obstructive jaundice before surgery. This is because Vitamin K needs bile to be absorbed fromContinue reading “Learning fascinating stuff 02”
