Question

Q: discuss the cellular movement of K+ in acidosis as compared to alkalosis

Answer 1

Answer :

• Potassium is critical For many biochemical cellular reactions .
• The body maintains potassium concentration primarly through the action of kidneys .
• Potassium is freely filtered by the glomerulus .it is actively reabsorbed in a proximal tubules .
• The potassium concentration can be affected at the cellular level by a number of factors .
• The pH of the extracellular environment is one of the major influence on potassium serum concentration .
• Acidic conditions promote the cellular uptake of H+ to maintain homeostasis .For each H+ taken up by the cells , a K+ is moved extracellularly to preserve electroneutrally .
• Alkalosis has the opposite effect , promoting cellular uptake of K+ in exchange for H+ .
