plz ask me all toughest and logical questions u can abt cell membrane and ribosomes!?

Question

i know it may sound silly but plz ask questions frm me as i hv to attend discussion class abt this topic tommorrow!

Answer 1

The obvious one is:
1) Describe synthesis of proteins ie where does it occur, how does it occur etc.

3) What is a) exocytosis?
b) pinocytosis?
c) pahgocytosis?
4) Describe the structure of the cell membrane according tho the Fluid Mosaic model.
5) Why does water move in and out of cells easily?
6) Describe the transport of a) ions?
b) proteins?
across the cell membrane.
7) True or false: a) The cell membrane is composed of 2 layers?
b) Proteins that span the membrane are integral
c) Cell membrane is a lipid bi-layer
d) Consists of hydro- phobic and -phiic parts
e) Is impermeable to water
f) Is permeable to carbohydrates
8) What is the function of endoplasmic reticulum?
9) What is the diff btwn rough and smooth Endoplasmic retic.?
10) What are ribosomes responsible for? What type of DNA or RNA do they receive. Name the process that takes place at ribosomes.

Answer 2

OK, here's one that poses an interesting conundrum for a biology teacher - see if they come up with the right answer.

If a virus replicates itself by inserting it's DNA through the cell wall into the interior, then kills the cell when it ruptures and releases all the new viruses it was forced to create, why can't we fight viruses by finding a compound that makes the cell walls impenetrable to viruses?

The answer of course is that if the cell wall is impenetrable, the cell itself would die anyway for lack of the permeability it needs to trade materials in and out.
