The cell/plasma membrane of a bacterium living in a salty aquatic environment contains a membrane channel protein called MelB. When this bacterium is placed in a hypertonic solution that models/mimics its natural habitat, MelB facilitates the uptake of the sugar melibiose along with sodium ions (Na+).a) What potential challenges might this organism encounter if it were deficient in membrane proteins responsible for moving charged particles across this boundary? Consider the salty environment (75 words, 1.5 marks).b) Explain how MelB functions to transport melibiose and sodium ions (Na+) across the membrane and what type of cellular transport mechanism does it use? (25 words, 1 mark).
