The signal transduction pathways that lead to physiological or developmental responses, these responses fall into two general categories;

a) Ion fluxes, which cause relatively rapid turgor responses

b) the possible chain of events constituting the signal transduction pathways that bring about these effects

c) Altered gene expression, which typically results in longer-term responses

d) Gene expression altered shows short-term response

Which of the following combinations from above given general categories is true?

Aqueous two phase partitioning (ATPS) is used for the recovery of an enzyme from the cell free culture filtrate on addition of PEG2000 and dextran. The mixture separates into two phases with a partition coefficient for the enzyme = 4.2. The maximum possible enzyme recovery, when the volume ratio of the upper to lower phases is 5.0 will be:
