Phospholipid Bilayer

1

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

1

What does hydrophobic mean?

1

What does hydrophilic mean?

1

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

1

What does semi-permiable mean?

1

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

1

Water
Gases
Glucose
Ions
Steroids

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

1

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.

1

In the diagram below, structure B represents:

Protein channel

Cholesterol

Phospholipid

Carbohydrate

1

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.

1

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

1

Which phrase best describes the property of selective permeability?

some molecules pass

all molecules pass

all ions pass

large molecules pass

1

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.

Diffusion

We will watch the video in class, but it is included here in case you need to review. Answer the questions on the slides, using the text boxes to the right.

1

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
Active Transport

password is math with your initials

This is a STEM Case, so all the work is done on Gizmos

Go back and forth between the case and the handbook

DO NOT SUBMIT THIS FORMATIVE! THERE WILL BE MORE SECTIONS TO DO!

Wait here until you are instructed to go on to the next section. If you are done early, be productive!
