Question

Graphs A, B and C (the dark line) represent the rates of influx (Y axis) of different (different molecule in A and B and C) across a membrane as the extracellular substrate concentration varies (X axis). Explain why these graphs have different shapes (C is linear, A and B are not) and what the shapes tell you about the mechanisms involved in these molecules getting across the membrane. (why are the lines not linear in B and C and what does that indicate, what does the linear line in A indicate?) molecules Extracellular substrate conc Extracellular substrate conc Extracellular substrate conc
