In this question, this is a multiple test and we have question number 41 and question number 42.
00:07
And for question number 41, we need to know what is an example of protein which is involved in active transport.
00:16
So basically in question number 41, the correct answer is the letter c, that is the sodium potassium pump, which is the correct answer.
00:30
Across the cell membrane, the movement of molecules against the concentration gradient, for example, from low concentration to high concentration, with the utilization of atp, which is known as the active transport.
00:54
The active sodium potassium pump present on the cell membrane allows the influx.
00:59
So there is an influx of sodium ions inside the cell.
01:12
And also there is an e -flux of potassium ions.
01:18
We have potassium ions outside the cell.
01:26
This potassium and sodium pump activity directly or indirectly affects the membrane potential...
