Chapter 5.1, Problem 2C
Summary Introduction
To draw: A simple sketch to illustrate how a transmembrane protein might be positioned in a lipid bilayer.
Concept introduction: Membrane proteins are a part of biological membrane that primarily interacts with it to perform various functions in the cell. There are various membrane proteins that help in the transportation of molecules in and out of the cell. Based on extend of attachment to the membrane, the membrane proteins are classified as integral proteins, peripheral proteins, and transmembrane proteins.
