This assignment is on Gizmos

Log in with my username MrsTAButler
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!

Water

Gases

Glucose

Ions

Steroids

Can pass through membrane

Needs a protein channel

Needs a protein channel + energy

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.

In the diagram below, structure B represents:

Protein channel

Cholesterol

Phospholipid

Carbohydrate

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.

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

Which phrase best describes the property of selective permeability?

some molecules pass

all molecules pass

all ions pass

large molecules pass

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

Active Transport
