24 Animal cells secrete procollagen which must then be modified before it can assemble into collagen Fibrils that strengthen the extracellular matrix What is this modification a Single stranded collagen polypeptides form dimers in the extracellular matrix b Single stranded collagen polypeptides form trimers in the extracellular matrix c Extracellular proteases separate procollagen polypeptides into single strands d Extracellular proteases cleave the ends of procollagen trimers e Kinase enzymes phosphorylate the collagen polypeptides
