... shape (10 μm unit length) produces 1 million molecules of insulin (molecular weight = 5600 daltons) that are stored in dense core secretory granules, each approximately 300 nm in diameter. Calculate the following: I) If the insulin-containing granules occupy 10% of the cell volume, how many ...
