The rate of simple diffusion of CO₂ through the cell membranes of lung cells in a crowded room (higher concentration of CO₂ in the air), in comparison to outdoors, is

Question

Quizplus · Accepted Answer

In a crowded room, there is a higher concentration of CO₂ in the air, which will result in a buildup of the gas in the lungs. This will create a concentration gradient between the lungs and the blood, which will initially enable faster diffusion of CO₂ into the blood. However, as more and more CO₂ enters the lungs, the concentration gradient will start diminishing, and eventually, there will be no net movement of the gas. Therefore, the rate of diffusion of CO₂ will slow down in the crowded room as compared to outdoors, where there is a lower concentration of the gas in the air.
