    'Explain the link between mitochondria in muscle cells and rough endoplasmic reticulum in enzyme secreting cells from salivary glands' - how do I link the two??

    Start by explaining the function of the two in the two cells, then you'll see the link. They're both extremely important for the cell's function.

    Mitochondria in muscle cells: contraction of muscle fibres by relative sliding of actin and myosin filaments requires energy - provided by mitochondria (explains why muscle cells have numerous, large mitochondria: Jesus, if you believe in the guy, was not silly!!) - salivary gland cell secrete salivary juice (contains salivary amylase [ptyalin]), which, of course, is a protein - hence well-developed ER in these cells (ribosomes = site of protein synthesis) - this process requires energy - provided by mitochondria (also well developed in salivary gland cells) - hence link.
