Proteins that assist in the movement of substances across can be classified into two types which are:
<h3>What are Proteins?</h3>
These are biological molecule which consists of amino acid sequences and are involved in metabolic activities in the body.
They are also found in cells and help in the selective movement of molecules in and out of the cell.
