The concentration of a biomolecule inside a rod-shaped prokaryotic cell is 0.0027 m. calculate the number of molecules inside the cell, which is 4.4 μm long and 1.2 μm in diameter.

Answer : The number of molecules inside the cell is,

Solution :

First we have to calculate the volume of biomolecule cell.

Volume = Area of the base of the cell × length of the cell

where,

V = volume of the biomolecule cell

r = radius of the cell =

h = length of the cell =

Now put all the given values in the above volume formula, we get

conversion :

Now we have to calculate the moles of a biomolecule of the cell.

Now we have to calculate the number of molecules inside the cell.

Therefore, the number of molecules inside the cell is,
