The diffusion time of the red blood cell to take oxygen through the membrane is 25uS.
The small capillaries in the lungs are in close contact and it takes a red blood cell 0.5 seconds to squeeze through the capillary.
The diffusion time for the oxygen across the 1 um thick membrane separating the air is given by,
t = x²/2D
Where,
t is the diffusion time,
x is the thickness of the membrane,
D is the diffusion coefficient.
Putting values,
t = (1 x 10⁻⁹)²/2 x 2 x 10⁻¹¹
t = 10⁻⁷/4
t = 25 x 10⁻⁹ seconds.
t = 25 uS.
so, the diffusion time is 25uS.

<u>Analyzing the answer options:</u>
<u>4(14.75)
</u>
- This may be correct as contains 4 as multiplier
<u>48.00) + 4.50 +2.25
</u>
- Incorrect as no multiplier of 4
<u>4(8) + 4(4.50) + 4(2.25)
</u>
- This may be correct as contains 4 as multiplier and the sum is same as the first option
<u>48.00 +4.50 +2.25)</u>
- Incorrect as no multiplier of 4
