Fluid Mosaic Model

Question 1

Fluid Mosaic Model

Answer 1

accounts for the presence of lipids, proteins, and carbohydrates in a dynamic, semisolid plasma membrane that surrounds cells

Question 2

The membrane is static

TRUE or FALSE

Answer 2

FALSE

the membrane is not static

Question 3

Lipids move freely in the plane of the membrane and can assemble into

Answer 3

lipid rafts

Question 4

_______ are specific membrane proteins that maintain the bidirectional transport of lipids between the layers of the phospholipid bilayer in cells

Answer 4

Flippases

Question 5

what can affect how fast or slow the proteins and carbohydrates move within the membrane?

Answer 5

their size.

They usually move slow because they are large

Question 6

The plasma membrane contains proteins embedded within the

Answer 6

phopholipid bilayer

Question 7

Cell (plasma) membrane

Answer 7

semi permeable phopholipid bilayer

Question 8

Carbohydrates associated with membrane - bound proteins create a

Answer 8

glycoprotein coat

Question 9

the cell wall of plants, bacteria and fungi contain (higher/lower) levels of carbohydrates

Answer 9

higher

Question 10

Lipid rafts

Answer 10

are collections of similar lipids with or without associated proteins that serve as attachment points for other biomolecules; these rafts often serve roles in signaling.
