Question 6

What is the water fearing or fatty acids tails?

Answer 6

Hydrophobic

Question 7

A protein that penetrate the lipid bilayer

Answer 7

Integral proteins

Question 8

Associated within the surface of the cell. It does not stick into the hydrophobic core

Answer 8

Peripheral Proteins

Question 9

Found on the outside surface and has 2-60 monosaccharide units, with a structure of straight or branched.

Glycolipids for lipids, Glycoproteins for proteins

Answer 9

Carbohydrates

Question 10

Makes cell membrane stiffer and in cooler temperature it pack tightly together, dense and fairly rigid

Answer 10

Saturated fatty acid

Question 11

Less tightly packed, increase its fluidity, in cooler temperature cannot pack together as tightly because of then bent structure of the tails

Answer 11

Unsaturated fatty acid

Question 12

Maintains fluidity across a wide range of temperature

Answer 12

Cholesterol
