The living things, on the basis of the name, are active and lively. They are composed of cells, and possess the features of life, like movement, growth, response to stimuli, reproduction, they possess the tendency to evolve, and need energy for their daily routines. Some of the usual examples of living things are animals, human beings, plants, and microorganisms.
On the other hand, the non-living things do not possess any features of life. They do not respire, grow, require energy, reproduce, move, maintain homeostasis, or evolve. These substances are made up of non-living components. Some of the examples are electronic goods, paper, stones, automobiles, and others.

<u>Answer</u>:
<em>Sodium potassium pump works by following several steps.
</em>
<u>Explanation</u>:
<em>1. Carrier protein binds three molecules of Na+
</em>
<em>2. ATP is split, phosphate bonds to carrier.
</em>
<em>3. Carrier protein changes shape, and deposits Na on the outside of the cell.
</em>
<em>4. Carrier binds two molecules of K
</em>
<em>5. Phosphate is released.
</em>
<em>6. Potassium is released inside the cell
</em>
Sodium -potassium pump is essential to maintain the concentration of sodium and potassium outside and inside the cell respectively.
It is the function of sodium potassium pump to transport sodium out of the cell and potassium inside of the cell against a concentration gradient.
<em>Thus it is an active transport mechanism.
