EOC REVIEW: CELLULAR RESPIRATION- Cell Membrane

Question 1

What is the fluid mosaic model?

Answer 1

Membranes are made of tiny pieces that move

Question 2

What keeps the fluid mosaic’s membrane mobile?

Answer 2

The unsaturated fatty acid tails

Question 3

What is the structure of the cell membrane?

Answer 3

The hydrophobic tails, which are made up of on saturated fatty acid, face inwards, and the hydrophilic head, made of one unsaturated fatty acid, faces outwards.

Question 4

Are saturated fatty acids bent or straight?

Answer 4

They are straight.

Question 5

Are unsaturated fatty acids bent or straight?

Answer 5

Bent

Question 6

What is the cell membrane (what type of things are allowed to go through)?

Answer 6

Selectively permeable

Question 7

What can easily pass through the cell membrane?

Answer 7

Nonpolar, hydrophobic molecules.

Question 8

What cannot easily pass through the cell membrane?

Answer 8

Polar, hydrophilic molecules cannot easily pass through.

Question 9

What do polar, hydrophilic molecules need to pass through a cell membrane?

Answer 9

They require proteins.
