The answer to this question would be: <span>producing large quantities of proteins for secretion
Cell with many smooth endoplasmic reticulum has a high protein synthesis capability. This will make the cell able to produce many proteins like enzyme. One example of this type of cell will be hepatocyte or cell in the liver. This cell will need many enzymes to detoxify toxin in the body.</span>
