Once in the epithelial cells, the macromolecules are degraded and used in the synthesis of proteins in the well-developed rough endoplasmic reticulum (Palade 1975) and lipid synthesis in the smooth endoplasmic reticulum (Cormack 1987) to help fuel cellular metabolism and contribute to the protein and lipid constituents of the cuticle covering the gill epithelium (Hadley 1994; Neville 1998).
