Ans. is 'a' is inner mitochondrial membrane .Ratio of protein to lipid in different membranes.Inner mitochondrial membrane -3.2 (Max.)Sarcoplasmic reticulum -2.0Outer mitochondrial membrane -1.1Myelin-0.23 In almost all the membranes of the body proteins are equal or exceed the quantity of lipid. The only exception is myelin (high lipid content provide good insulation).
