sodium-potassium pump- blue

when does the pump have a high affinity for sodium?

when it is open towards the intracellular side

how many sodiums need to bond to open up the binding site for ATP?

3

what is phosphorylation?

when a phosphate group is added- resulting from ATP hydrolysis

what does phosphorylation cause?

the pump to change shapewha

what does ATP turn into after ATP hydrolysis?

ADP

what happens after the pump changes shape

the 3 sodium are released into the extracellular environment

what is the affinity in a phosphorylated pump?

low for sodium, high for potassium

how many potassium need to bond for dephosphorylation to happen?

2

what does dephosphorylation cause?

the pump to change shape- open towards the intracellular environment

what is the charge of the resting cell?

negative

what is the charge of sodium?

positive

what is the charge of potassium?

positive
