One strong possibility for the cause of this scenario is a hoof abscess--a localized accumulation of pus within the horse's hoof. The good news is that abscesses can often be resolved quickly and easily with proper veterinary care and leave no lasting damage.
A: The sodium-potassium pump is an essential cellular membrane protein that functions by pumping out three sodium ions and taking in two potassium ions. This mechanism preserves the electrochemical gradient formed from the varying concentrations of sodium and potassium ions within the cell and its exterior. Continue Reading
By means of the sodium-potassium pump, living human cells pump three sodium ions out of the cell in exchange for two potassium ions pumped in; comparing ion concentrations across the cell membrane, inside to outside, potassium measures about 40:1, and sodium, about 1:10.
