lysosome

Post by mkw743 » Sat Oct 29, 2005 2:31 pm

would anyone please explain to me why the hydrolytic enzyme inside lysosome would not self-digest the cell membrane of lysosome
Thank you

All the proteins on the inner membrane of the lysosome are glicosilated to prevent self-digestion. But some special sugars are used, in order to prevent self-digestion of them by the glicosydases(translation probably wrong :lol: )

Simply: there are structures that prevent the enzyme to link to tha substrate.

but how do the lysosomes digest the entire cell at times. i mean they would have to digest themselves along with the cell if it is damaged
right? :? :?

If it is damaged, yes the cell digests itself.

@Andrew:
Yes something like that. :) Not all of your posts ;)

lysosomes dygest whole cells in very long periods of times... take for example being born... lysomes take nine months to form fingers for your hand or toes for your feet... and of course preventing deformities like havng a tail or webbed feet

Each lysosome is surrounded by a membrane that protects the cell from the lysosome's digestive

enzymes-if the lysosome breaks open, the enzymes would destroy the cell. Proteins embeded in the

lysosome membrane protect the activity of the enzymes by maintaining the proper internal acidity.
