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 (10[1])facilitate (10[2])transverse movement between their leaflets. An early sign of apoptosis is the formation of blebs in these structures. The rigidity of these structures at varying temperatures (10[1])is controlled (10[1])by their cholesterol content. (10[2])Proteins in these structures (10[1])may be classified as “peripheral” (10[1])or “integral.” (-5[1])The fluid mosaic model of these structures describes how (10[1])channel proteins are embedded in their phospholipid bilayers. (10[1])For 10 points, name these structures that separate the interior and exterior of cells. ■END■ (10[1]0[1])
