Phospholipid Bilayer

Question 13

13.

Sketch a picture of a single phospholipid, label the hydrophobic and hydrophilic parts

Question 14

14.

What does hydrophobic mean?

Question 15

15.

What does hydrophilic mean?

Question 16

16.

Sketch a picture of the cell membrane. Label the heads/tails of the phospholipids, the inside and outside of the cell, and the proteins.

Question 17

17.

What does semi-permiable mean?

Question 18

18.

What can go through the phospholipid part of the cell membrane? What needs a protein channel?

Question 19

19.

Water
Gases
Glucose
Ions
Steroids

Can pass through membrane
Needs a protein channel
Needs a protein channel + energy

Question 20

20.

Which of the following is a function of the cell membrane?

Breaks down lipids, carbohydrates, and proteins from foods.

Stores water, salt, proteins, and carbohydrates.

Keeps the cell wall in place.

Regulates what materials enter and leave the cell.

Question 21

21.

In the diagram below, structure B represents:

Protein channel

Cholesterol

Phospholipid

Carbohydrate

Question 22

22.

The phospholipid bilayer describes a structure with:

Polar heads on the outside and non-polar tails on the inside.

Non-polar tails on the outside and polar heads on the inside.

Polar layers on both the inside and outside.

Non-polar layers on both the inside and outside.

Question 23

23.

If all materials were allowed to cross the cell membrane, then a cell’s contents would be the same as its surroundings. This does NOT happen because the cell membrane is:

Permeable

A fluid mosaic

Selectively permeable

In dynamic equilibrium

Question 24

24.

Which phrase best describes the property of selective permeability?

some molecules pass

all molecules pass

all ions pass

large molecules pass

Question 25

25.

One of the functions of proteins in a cell membrane could be:

To allow larger molecules to pass through the cell membrane.

To make sugar for the cell.

To provide nutrients to phospholipids.

To transform light into usable energy.

Goes against the gradient
Goes with the gradient
Osmosis is a type of this
Uses the membrane
Uses protein channels
Uses energy
Exocytosis is an example of this (even though it doesn't use protein channels)
Endocytosis is an example of this (even though it doesn't use protein channels)

Simple Diffusion
Facilitated Diffusion
