Answer 1

- By binding to the guanine nucleotide exchange proteins that activate the Rabs certain effectors act to establish positive feedback cycle that help to define and maintain tightly localized domains of activated Rab proteins, which then serve to recruit other effector molecules
Negative feedback is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often it causes the output of a system to be lessened; so, the feedback tends to stabilize the system .
