Question

How many glucose molecules does the cell in Problem 18 contain when its internal glucose concentration is 1.0mM ?

Short answer

The number of glucose molecules present in a cell with 1.0mM internal concentration for glucose molecule has 3.2 $\times$ 10⁵molecules.

Step-by-step solution

Given data

Glucose concentration is 1.0mM.

Molar concentration is 1.0 $\times$ 10^-3 molL^-1.

Volume is 5.24 $\times$10^-16 L.

Calculate the number of glucose molecules

Number of Molecules = Molar Concentration $\times$Volume $\times$6.022 $\times$10²³ molecules mol^-1

= (1.0 $\times$ 10^-3 molL^-1)(5.24 $\times$10^-16L)(6.022 $\times$10²³ molecules mol^-1)

= 3.2 $\times$10⁵ molecules

Conclusion

As a result, in a cell with a 1.0mMinternal glucose concentration, there are 3.2 glucose molecules present.
