Glucose is a main energy-yielding nutrient for most cells. Presuming a cellular concentration of 1 mM, compute how many molecules of glucose would be present in our hypothetical as well as spherical eukaryotic cell. Avogadro's number, the number of molecules in 1 mol of a non ionized substance, is 6.02 X1023).
