Question

question 11
match each cell membrane concept (column a/left side) with the correct description or function (column b/right side).
note: there are more options in right side column than are needed.
column a

1. phospholipid bilayer
2. cholesterol
3. peripheral proteins
4. integral proteins
5. glycoproteins
6. selective permeability
7. fluid mosaic model

column b
a. loosely attached to the membrane surface, often for signaling or structural support
b. model describing the membrane as flexible with proteins and lipids moving within it, and cholesterol in many eukaryotic cells
c. rigid and impermeable providing a waterproof barrier
d. involved in forming ribosomes for protein synthesis
e. proteins embedded through the entire bilayer, often acting as channels, pumps or transporters
f. polar heads face outward, nonpolar tails face inward
g. attached, carbohydrate chains important for cell recognition and signaling
h. helps stabilize membrane fluidity in varying temperatures
i. allows the membrane to control which substances enter or leave the cell

Explanation:

Each concept in Column A is matched to Column B based on its defining structure or function.

Answer:

1. f
2. h
3. a
4. e
5. g
6. i
7. b
