00:01 Question one discusses about the sodium potassium pump.

00:04 So, this sodium potassium pump is one particular kind of system which in turn would require energy.

00:13 And this energy is in turn supplied in the form of atp.

00:17 Atp in turn stands for adenosine trifosate.

00:21 And a main function of the sodium potassium pump is to transport the sodium ions return as enablus to move it out of a particular.

00:30 Cell whereas the other one it is the potassium ions return is caveless so this intern needs to be moved into a particular cell and this intern is done to maintain the concentration of ions across both the side of the cell so here c -onc intern denotes concentration as because it requires energy in the form of atp this can also be referred to be as an atp as because it is in turn involved in because this intern requires the energy in the form of atp.

01:01 But it should be noted that the concentration of sodium is in turn found to be higher outside the cell, whereas that of potassium is in turn found to be inside the cellar.

01:12 So as because it is higher and against the concentration gradient, this intern requires the energy in the form of atp.

01:19 So this is the one with regard to the mechanism of this particular processor.

01:25 And next to it, it is the membrane potential.

01:28 The membrane potential in turn denotes the potential that is the potential which is in turn added to a particular membrane or the potential value of a particular membrane.

01:38 So this intern is always compared with inside to that of the outsider.

01:43 So it is always found to be negative for most of the cell and then the value then sorry another value is in turn identified to be 70 million older.

01:52 So this in turn denotes the negative feature of within the inside of the particular membrane.

01:58 So this value in turn denotes the resting membrane potential of a particular cell up.

02:04 So this in turn denotes that a particular cell is always negative with inside to compare to that of the outsider.

02:12 So there are certain channels which are in turn referred to be as the leakage channel.

02:17 So this leakage channel can allow the sodium ions to move out of a particular cell and then the potassium ions to move into a particular cell along the concentration gradient...
