Question

estimate the number of hemoglobin molecules in a red blood cell. red blood cells are little more than bags of hemoglobin, so it is reasonable to assume that the hemoglobin takes up all the volume of the cell.

Answer 1

Each human red blood cell contains approximately 270 million of these hemoglobin molecules.

Answer 2

Answer:

2.51e8 molecules per cell

Explanation:

We take the volume reported of a blood red cell wich is 87 μm^3

And the volumen of hemoglobin: 321.6 nm^3

So we have 87 μm^3 = 8.7e10 nm^3

N=Number of hemoglobin molecules

N=8.7e10/321.6=2.51e8 molecules per cell
