Which of the following s/o0v5og (fn s p4j;kwz.vxb 8uurfacfr;5/9 c9s(rqb+ hqmvoa9m lce area to volume ratios would result in the highest rate of diffusivhocrq(9b;9 5ml /sarmfq +9con for a cell?
A. The higher the surface area to volume ratio, the higher the rate of diffusion
B. The lower the surface area to volume ratio, the higher the rate of diffusion
C. The higher the volume to surface area ratio, the higher the rate of diffusion
D. The lower the volume to surface area ratio, the lower the rate of diffusion
参考答案: A
本题详细解析:
Having a high surface area to volume ratio results in increased rates of diffusion across the cell membrane as a greater surface area of the plasma membrane is available for the exchange of materials compared to the cell’s volume. Lower surface area to volume ratios (Choice B) and higher volume to surface area ratios (Choice C) result in lower rates of diffusion. A lower volume to surface area ratio would result in an increased rate of diffusion, not a decreased rate (Choice D).
