You are studying passive diffusion of a molecule called FLUBBER across a semipermeable
membrane, which is mimicking the phospholipid bilayer of eukaryotic cells. FLUBBER moves
from side A to B. Which of the following can you conclude?
Side A had a lower FLUBBER concentration initially compared to side B.
Side A had a higher FLUBBER concentration initially compared to side B.
Side A had the same initial FLUBBER concentration as side B
