Why is there more oxygen taken up by normal red blood cells than spherical cells?

Answer 1

I am confused with the question, but if you mean "http://wiki.answers.com/Q/Why_is_there_more_oxygen_taken_up_by_normal_red_blood_cells_than_spherical_cells" then i may be able to help: RBC function is greatly dependent on shape, which is why with people sickle cell anemia carry significantly less oxygen than healthy people. The shape of normal RBCs, functions to increase their surface area, for more effective gas exchange. A spherical RBC's surface area is not sufficient enough to carry the same amount of O2.

Answer 2

i was working out some medical entrance questions and the was kind of this same question .

it said that this was because biconcave cell have 20-30% more surface area than spherical cells. hope it helps.

PARADOX

Answer 3

Normal red blood cells have a biconcave shape, which provides a larger surface area for oxygen exchange compared to spherical cells. This increased surface area allows more oxygen molecules to bind to hemoglobin in the red blood cells. Additionally, the biconcave shape allows red blood cells to be more flexible and navigate through narrow capillaries to deliver oxygen more efficiently.
