Round 8: Tossup 12

A constituent of these biological structures called DSPC is used in the formulation of several mRNA vaccines. These structures’ flippases and scramblases facilitate (10[1])transverse movement between their leaflets. An early sign of apoptosis is the formation of blebs in these structures. (10[1])The rigidity of these structures (-5[1])at varying temperatures (10[1])is controlled by their cholesterol content. Proteins in these structures may be classified as “peripheral” or “integral.” The fluid mosaic model of these structures (10[1])describes how channel proteins are embedded in their phospholipid (10[1])bilayers. (10[1])For 10 points, name these structures that separate (10[1])the interior and exterior of cells. ■END■
