1) How many hemoglobin molecules are there in an average red cell? Assume that the molecular weight of the human hemoglobin tetramer is 65 kd. (The answer is 2.74x10^8, but I don't know how to calculate it). 2) Could the hemoglobin concentration in red cells be much higher than the observed value? (Hint: Suppose that a red cell contained a crystalline array of hemoglobin molecules in a crystalline array of hemoglobin molecules in a cubic lattice with 65 A sides.)
