    The thickness of unit membrane is

    A)  \[\text{20}\overset{\text{o}}{\mathop{\text{A}}}\,\]

    B)  \[35\overset{\text{o}}{\mathop{\text{A}}}\,\]

    C)  \[55\overset{\text{o}}{\mathop{\text{A}}}\,\]

    D)  \[75\overset{\text{o}}{\mathop{\text{A}}}\,\]

    Correct Answer: D

    Solution :

    The unit membrane, described by J David Robertson, was considered as \[\text{75}\overset{\text{o}}{\mathop{\text{A}}}\,\]thick trilaminar (3 layered membrane). According to his unit membrane or trilaminar model, unit membrane consists if \[35\overset{\text{o}}{\mathop{\text{A}}}\,\]thick bimolecular phospholipid layer between two protein layers, each with \[\text{20}\overset{\text{o}}{\mathop{\text{A}}}\,\]thickness.
