The building blocks of the ion channels in cell membranes are
A)lipids.
B)amino acids.
C)sodium ions.
D)potassium ions.

Question

Quizplus · Accepted Answer

The building blocks of ion channels are proteins. Proteins are made up of amino acids, which are arranged in a particular sequence to form the ion channels. Lipids are not the main component of ion channels, although they do make up cell membranes in which ion channels are embedded. Sodium ions and potassium ions are not building blocks of ion channels, but rather they are the ions that pass through the ion channels.
