Question

could someone give me a picture showing where the hydrophobic part of a cell membrane is located please?

Answer 1

Here's a hint: hydrophobic means afraid of water. Hydrophilic (water loving) parts like to be close to the surrounding water, and hydrophobic (water fearing) parts will stick together away from the water.

Answer 2

so is it on the outside since water can be inside the cell?

Answer 3

Water is both inside and outside the cell.

Answer 4

so its IN the membrane?

Answer 5

Yes. Look at the phospholipids. See that tail? That's the hydrophobic part. The head is hydrophilic, and that's why they arrange themselves in a bilayer.

Answer 6

the problem im trying to solve says this The hydrophobic part of a cell membrane is on the inside of the phospholipid bilayer.
True
False

so its true?

Answer 7

Yes. Incidentally, proteins have hydrophobic and hydrophilic parts too: for proteins in the cytoplasm, the hydrophobic part is hidden on the inside (away from the water) and the hydrophilic part is on the outside (in contact with the water). In membrane proteins, it's a bit more complicated, because they can have hydrophobic sections inside the hydrophobic part of the membrane.

Answer 8

oh ok thanks for th help!

Answer 9

Answer 10

No problem!
