Receptors transferrin

Hey, for the number of transferrin receptors in each coated pit I've got: 100 000 receptors, 70% localised within the coated pits so: 100 000 ...

... 68micrometers squared. The next question is to then calculate how many transferrin receptors there are in each coated pit, but I just can't get my head round how to do that.

... vesicle that will be formed from it. If the cell surface has 100,000 transferrin receptors, around 70% are localised within coated pits: work out how many coated pits there ...

... out! Think I've got the answer to number 5 too. 5. There are 100,000 transferrin receptors, 200,000 are bound. We need equal concentrations of bound and unbound receptors, ...

... answers, not sure if correct though: 3. Concentration in pits: 70,000 receptors (70% of 100,000) / 68 (2% of 3400- the surface area covered in ... * Avagadro (6.022 *10^15) =6.022 * 10^15 - 200,000 (molecules of Transferrin needed) =6.002 *10^15. Thats all I've done so far. Do you know ...
