fluid mosaic model

Question 1

what’s in a fluid mosaic model?

Answer 1

Peripheral protein
Channel protein
Carrier protein
Glycoprotein
Cholesterol
phospholipid

Question 2

Integral protein is a…?

Answer 2

Channel protein and carrier protein
Goes in the bi-layer

Question 3

Peripheral protein means

Answer 3

It doesn’t go all the way through the bi-layer

Question 4

mass flow -
Diffusion-
osmosis-

Answer 4

mass flow- Substance high-low pressure
Diffusion- Gas high-low concentration
Osmosis- Water high-low concentration

Question 5

Facilitates diffusion + osmosis need what

Answer 5

Need proteins

Question 6

passive transport

Answer 6

requires no energy

Question 7

active transport

Answer 7

requires energy

Question 8

simple diffusion

Answer 8

small molecules can diffuse down the bi-later on their own because they are small enough too.

Question 9

Facilitated diffusion

Answer 9

Some larger molecules have to use a transmembrane protein because to larger or too polar.
