    Yes i rejected D because it wont be permeable to ions and large molecules so word increase was wrong in that. I guess

    One i chose was temp+ i dont remember it was D And permeabilty would be increased if more protein channels are there. I guess that was B option. Bad memory i have. And recoiling one.A

    The question was to find unknown concentration of amylase in the extract of fungus. And we didnt have to verify the trend. The trend given was suppose to be used in calculating the concentrations. Threshold is gonna be 21-23 because this question was a bit tricky.
