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