plasma membranes - 2025 PACE NSC

Question

Taib et al. 2020 argues that the loss of a type of these structures evolved repeatedly in Terrabacteria. A cysteine in the N-terminal head of Lpp secures it to one of these structures. These structures can feature beta-barrel-shaped (0[1])proteins like OmpF. (0[1])Lipid (0[1])A and O antigen appear in the lipopolysaccharides (20[1]0[1])that jut out from one (0[1])of these (0[1])structures. (20[5]0[3])Electroporation alters these (20[1])structures, which are penetrated by (*) porins, (10[2]0[1])in order to (10[2])promote (10[2])transformation. (10[2])The presence of an "outer" one of these structures (10[2])in addition to the (10[1])"inner" one typically (10[1])implies Gram-negativity. (0[1])For 10 points, name (0[1])these semipermeable lipid (10[3])bilayers (10[1])that compose (10[1])the bacterial cell envelope alongside the cell wall. (10[1])■END■ (10[11])

ANSWER: plasma membranes [or cell membranes or bacterial cytoplasmic membranes or outer membranes or inner membranes; prompt on lipid bilayers until read; prompt on OMs or or IMs]
