cell membranes simple question

Which of the following is NOT a function of the intercellular membrane.

Cell to cell signalling, partially permeable membrane, site of chemical reactions, transport of substances across membrane
site of chemical reactions.


^^ it happens in the cytoplasm not the membrane

But my book says (last point on membranes within cells).

Partially permeable membrane?

That's a feature, not a function

Technically, your book is right BUT its not a function of the membrane as its mainly works as a barrier. But it does reactions such as in respiration the electron transport chain moves hydrogen ions across the membrane to generate ATP but generally I would've said the second thing you listed was untrue as its a feature not a function. Also, the cytoplasm is the MAIN site of chemical reactions

I did consider that, does it definitely transport substances across the membrane?

Is that even a question?!

Of course it does! Protein channels etc...

Okay thank you, that makes sense I'm going to go with partially permeable membrane not being a function.

I was just making sure. I know it does for the surface membrane but wasnt sure if its the same thing for the membranes within cells around organelles.
oh ****.. I really need to get the revision guide huh I didn't even know that :/

Membranes within cells is referring to the membranes of some organelles, not the cell membrane.

If anyone's curious the answer is "cell to
Cell signalling" this is NOT a function of the intercellular membrane becaus this membrane is around organelles. Organelles are not involved cell to cell signalling. Organelles are not cells.

Intercellular membranes?

Do you mean intracellular membranes? as that refers to organelles.

If you really do mean intercellular membranes (which actually doesn't make sense, it's just cellular membranes), then cell membranes can still participate in cell-signalling.

I meant intRAcellular that was autocorrect.

Don't call intracellular membranes "cell membranes."
