Made from a chain of amino acids known as POLYPEPTIDES.
"WORKHORSES" of the cell.
Functions
Receptors, transporters, enzymes, surface markers, adhesion mole-cules, and catalysts.
21. What is the proteolytic cascade with Eukaroytic cells?
ANS How proteins break-down and move.
Tightly orchestrated sequence of events that cause the breakdown of protein.
