Question

MEA I KNOW ABT SODIUM POTTASIUM PUMP......

Answer 1

Answer:

Na+ k+ pump are present in membrane of neurons. Use ATP for their function.

Na+ k+ pump are present in membrane of neurons. Use ATP for their function. They pump 3 Na + outside and 2 K+ inside.

Help in

1. Polarisiblity of membrane ( negativity charged inside, positively charged outside).

2. When neurons get any stimulus or impulse..

They allow to lots of sodium ions inside, changing the polarity of membrane of neuron.(polarity get reversed) . And action potential get generated.

Answer 2

hey mate!!

SODIUM POTASSIUM PUMP:

Active transport of ions takes place by the SODIUM/ POTASSIUM PUMP .

RESTING MEMBRANE POTENTIAL IS MAINTAINED BY THE ACTIVE TRANSPORT OF IONS AGAINST THEIR ELECTROCHEMICAL GRADIENT by sodium potassium pump.

→ These are the carrier proteins located in the cell surface membrane .

They are driven by energy supplied by ATP and couple are removal of three sodium ions from the axon with the uptake of two potassium ions .

hope it helps!!
