Does the muscle cell or the liver cell contains more smooth endoplasmic reticulum?

Question

blues · Answer

The smooth endoplasmic reticulum basically functions in nutrient metabolism, especially lipid metabolism. Does the liver or muscle tissue do more with breaking down nutrients?

anonymous · Answer

Liver : glucose to glycogen   (but isnt smooth ER is for lipid metabolism..so are they related)
Muscle : mostly using carbs i guess?

anonymous · Answer

oh..if you say breakdown, then it is liver cell

blues · Answer

I think it's liver.

Muscle cells are specialised to contract and produce motion. Liver cells are specialised to break down and store nutrients.

I think I remember hearing a fun fact from one of my professors that alcoholics will have more smooth endoplasmic reticulum in their livers since their body has acclimated to detoxifying themselves of all the extra toxins they ingest.

anonymous · Answer

lol then can i make an assumption that alcoholics will also contain more peroxisome? :)

kainui · Answer

I don't see why not! =D Next time you see someone with a high alcohol tolerance you can admire their increased numbers of peroxisomes!

blues · Answer

I didn't know that alcoholics have more SER in their hepatocytes, but it mkes sense. I did know that alcoholics freqently have much enlarged livers with more hepatocytes.

Somewhere I read that, on autopsy, Ernest Hemmingway's liver was six times bigger than normal human being's. Always remembered that one.
