本書介紹關於ER (Endoplasmic reticulum)

列出左幾句講ER的特點..但我唔係好明..

有心人請教教我..Thx

Endoplasmic reticulum
-It is a network of interconnected of membrane-bounded sacs.
(姐係點？我唔係好明咩係membrane-bounded sacs...)

-The ribosomes on rough ER are the sites of protein synthesis.Smooth ER is involved in the synthesis and transport of lipids.

( " rought ER are the sites of protein synthesis " 係指已合成既會放係ribosomes定係protein會係ribosome到合成,定係ribosome等於果d protein synthesis ?)
(之後講smooth ER果句我都唔係好明，請教教我.thanks)

**謝謝指教。(唔識既人唔好亂答or是但俾個網址我。)
Thank you.

-The ribosomes on rough ER are the sites of protein synthesis.Smooth ER is involved in the synthesis and transport of lipids.

( &amp;amp;quot; rought ER are the sites of protein synthesis &amp;amp;quot; 係指已合成既會放係ribosomes定係protein會係ribosome到合成,定係ribosome等於果d protein synthesis ?)
(之後講smooth ER果句我都唔係好明，請教教我.thanks)

~rought ER只是提供位置俾ribosomes synthesis protein和幫助ribosomes transport 已製造的proteins
~所以,ribosomes係製造proteins
~smooth ER參與製造和運送lipids
ps.smooth ER仲有製造carbohydrates and other non-protein products

Endoplasmic reticulum

~依個我都唔係好肯定,所以唔答你喇,sorry
不過如果你仲想知,send e-mail俾我,我幫你問我miss呀;)
ps你本書係唔係textbook?

參考: biology textbook
