[prokaryotics]

Hey just been pondering over this question for a while some help would be greatly appreciated.

"Under what circumstances would you expect a cell to increase the amount
of its smooth endoplasmic reticulum?"

So my ideas
= Increase in presence of drugs/poisons as the Smooth ER has the function of detoxifying drugs and poisons, a cell such as a liver cell will thus require a lot more Smooth ER in these types of conditions (to prevent damage)

cant think iof much more

thanks alot

yeah, that seems reasonable.

What about need for more lipids in fast growing cells?

[prokaryotics]

Ah sounds good, um Smooth ER also stores Ca+ ions, could we relate something to muscular action?

And any tips on the structuring of my answer cheers

[jwalin]

if its used as Ca2+ store (i aint sure of that) then it can be used in muscle cells, Beta cells of islets of langerhaans and at pre synaptic knobs.

i don’t think fast growing cells have an enlarged smooth ER..
Though hepatocytes and myocytes are good examples
