cell structure

Post by Marucs12345 » Wed Sep 21, 2005 4:07 am

What are particles of stored materials, and the word has 10 letters in it and a U for the 5th letter and an I for the 7th letter. Also are permease protein carrier molecules in the membrane?

For the word what about inclusions? (like inclusion bodies).
The permease as far as I know is lacY, the protein which allows lactose to enter the cell. (and be the substrate for the lacZ gene product beta-gal). I think it makes a sort of hole in the membrane not active carrier.

I can explain permeases if you wish. But i need to know what level you are studying...

Same concept; only it allows a few substances to difuse across it.
