Okay, one of the tons of this question, let's talk about the sodium potassium atpas.
00:03
Okay, this is the membrane.
00:06
You're going to have the sodium potassium aps here.
00:13
This sodium potassium atp is a type of active transport that is going to work, three sodium ions out of a cell, and two potassium in exchange for two potassium ions inside of the cell.
00:26
Okay, and as it is an active transport because it moves these ions like up the concentration gradient is going to use atp.
00:36
So, potassium, remember that the concentration of potassium are normally high inside of the cell and are normally low in the extracellular portion.
00:50
Okay? so the question says, potassium is a necessary nutrient in order to maintain the function of our cells.
00:56
What would occur to a person that is deficient in potassium? it means if there are even low levels of potassium here.
01:02
Okay, so if there are low levels of potassium, then there is not going to be potassium to move inside of the cell, okay? because practically there is no potassium here.
01:11
So if you don't have potassium to move, then this part is going to be blocked.
01:15
And as this is an antiportar, it means you exchange sodium by potassium...
