Question

17.Below is a diagram of a transmembrane protein with a single alpha helix found in the cell membrane. Can this helix serve as a transmembrane channel? Yes it can transport small molecules, because the central vertical axis is completely open Yes it can transport small molecules, because the central vertical axis is filled with water, which can move out of the way a. b. axis is filled with AA side chains d. No it cannot transport small molecules, because the central vertical axis is filled with tightly pack atoms from the protein backbone.

Explanation / Answer

17 b)) The helix can serve as a transmembrane channel yes it can transport small molecules because the central vertical axis is filled with wate,which can move out of the way.

Transmembrane channel are also called as membrane channel,are pores within the lipid bilayer of the cell membrane.The channel are formed by large protein complexes that run across the membrane connecting to the cytosol.
