<prompt> All are true about hepatocytes, EXCEPT:60 of the livers cell number are formed by hepatocytesContains crystals of ferritin and haemosiderinContains enzyme urease in distinctive crystalline formsNone of the above  <response>: About 80 of the liver volume and 60 of its cell number are formed by hepatocytes parenchymal cells. Their cytoplasm typically contains much rough and smooth endoplasmic reticulum, many mitochondria, lysosomes and well-developed Golgi apparatus, features indicating a high metabolic activity. Glycogen granules and lipid vacuoles are usually prominent. Numerous, large peroxisomes and vacuoles containing enzymes, e.g. urease in distinctive crystalline forms, indicate the complex metabolism of these cells. Their role in iron metabolism is shown by the presence of storage vacuoles containing crystals of ferritin and haemosiderin.
