Cell Membrane

Question 0

Glycoproteins function

Answer 0

Similar to glycolioids….

Allows communication between cells, identification, receptor sites for hormones

Question 1

Glycolipid functions

Answer 1

Receptor sites for hormones, identification- (for either self or non self )
Allows communication with other cells

Question 2

Channel proteins function

Answer 2

Allows molecules to diffuse in and our of the cell

Question 3

Phospholipid bilayer function

Answer 3

Forms the majority of the cell. Separates the inside from the outside

Question 4

Cholesterol function

Answer 4

Helps proved structure, maintains fluidity when cold and helps hold together when hot. Allows more temp

Question 5

Membrane proteins function

Answer 5

helps to give the membrane a little bit of structure, site for different reactions inside the cell

Question 6

Cell membrane function overall

Answer 6

DOES NOT GIVE STRUCTURE
control entry and exit of substances
Separate from outside.

Question 7

Fluid mosaic model what does ‘fluid’ and ‘ mosaic’ refer to

Answer 7

‘Fluid’ movement of the phospholipid belayer, rotate on axis and swap with others nearby.
‘Mosaic’ not structured arrangement
THESE MOVEMENTS INCREASE THE FLUIDITY OF THE MEMBRANE

Question 8

3 main components of the cell membrane?

Answer 8

Phospholipid
Protein
Cholesterol

Question 9

Structure of a phospholipid

Answer 9

Polar head - choline and phosphate
Glycerol backbone
Fatty acid chains

Question 10

Explain double bonds in the fatty acid chains

Answer 10

Cause kinks allowing the phospholipid hydrophobic tails to join together
