Question #92515

Glucose is the major energy yielding nutrient for most cells. Assuming a cellular concentration of 1 mM, calculate how many molecules of glucose would be present in our hypothetical (& spherical) eukaryotic cell of size 50 micrometer.

Expert's answer

As hypothetical cell is spherical we can apply equation for the volume of sphere:

where **d** is diameter (size) of the cell.

Concentration of glucose in the cell is

where **n** is the amount of glucose in moles and **V** is the volume of cell.

Number of molecules is linked to the number of moles via Avogadro's number:

Combining together all three equations, we can find number of glucose molecules in the cell:
