Although lipids are largely responsible for providing and maintaining the structure of the cell membrane, most of the membrane's functions are due to the proteins that are present in it. embrane proteins can be classified as integral or peripheral, depending on how they are positioned in the phospholipid bilaver. Based on figure 12, differentiate integral and peripheral proteins. Write your answer on the table below.
