Biochemistry Part 3: Hydrophobic and Hydrophilic

Question 1

What does Hydrophobic mean?

Answer 1

Water Hating.

Question 2

What does Hydrophilic mean?

Answer 2

Water Loving.

Question 3

Are nonpolar molecules hydrophobic or hydrophilic?

Answer 3

They are hydrophobic.

Question 4

Substances that are —– will dissolve in water, because—

Answer 4

Polar, because they are hydrophilic.

Question 5

Substances that are—- will not dissolve in water, because—.

Answer 5

Nonpolar, because they are hydrophobic.

Question 6

Carbon dioxide is polar or nonpolar? Why?

Answer 6

Non polar because it does not dissolve in Water.

Question 7

Lipids are polar or nonpolar? Why?

Answer 7

Non polar because they do not dissolve in Water.

Question 8

Water is polar or nonpolar? Why?

Answer 8

Polar because it dissolves in Water.

Question 9

Why can Non polar molecules dissolve in Plasma Membrane and Polar ones cannot?

Answer 9

Plasma membrane is a phospholipid bilayer(nonpolar) which makes nonpolar dissolve easily and large polar molecules cannot.
