Document Summary
Liver cells are called hepatocytes and liver is the major organ for lipid metabolism. Therefore, hepatocytes have large amounts of smooth er because it is involved in metabolizing lipids and the smooth er is not only for lipid synthesis but also for lipids to be packaged into larger particles called lipoprotein particles. Lipids and proteins come together to form particles and these particles are soluble in the bloodstream and can be transported by the bloodstream: liver is also involved in detoxification. It has a bunch of enzymes that cleans our system and get rids of toxic by- products. So the liver needs the smooth er to serve both of these functions: muscle also have lots of smooth er because it needs to store calcium. This type of er is called sarcoplasmic reticulum. When calcium is taken back up by the sarcoplasmic reticulum, it causes.
