Morphology

transmembrane = membrane (transparent) = trans + membrane

Meaning is a straightforward combination of the productive prefix 'trans-' ('across') and 'membrane' ('cell layer'), giving 'across a membrane'.

Etymology

Transmembrane comes from the prefix trans- meaning 'across', as in transport, and membrane meaning a thin 'skin' around a cell, so it describes something that passes or extends across a cell membrane.
