Which statement below regarding membrane structure and membrane transport is true? Increasing the proportion of unsaturated fatty acids of membrane would be most likely to occur as environmental temperature become warmer. Cyclization of membrane fatty acids (like cyclopropane) would confer more rigid straighter hydrocarbon chains Membrane lipids of by hyperthermophilic archaebackeria are of the ester-linked fatty acid type also found in non- and eukaryote membranes, respectively. Cell wall-containing and tend to possess a slightly hypotonic to create a positive pressure helping it to maintain cell shape and form. Group translocation is a transport mechanism that moves molecules via facilitated diffusion.
