Answer
The rate of diffusion of a molecule across a membrane is influenced by its removal from the area by the bloodstream or biological pathways.
Solution
a
Concentration Gradient: The removal of the molecule by the bloodstream or biological pathways maintains a high concentration gradient across the membrane, which can increase the rate of diffusion according to Fick's Law of Diffusion
b
Steady-State Condition: Rapid removal of the molecule prevents it from accumulating on the other side of the membrane, helping to maintain a steady-state condition where the rate of diffusion remains constant
Key Concept
Concentration gradient and steady-state condition
Explanation
The continuous removal of the molecule by the bloodstream or biological pathways maintains a high concentration gradient and prevents accumulation, thereby sustaining a higher rate of diffusion.
◊How does the rate of diffusion of a molecule change if it is quickly removed from an area by the blood stream or biological pathway? 

Formula: Rate of diffusion = (Surface area * Concentration gradient * Permeability) / (Membrane thickness * Molecular weight⍭ Generate me a similar question◊
