100
What the cell membrane is mostly composed of
What are phospholipids
100
Diffusion happens anytime there is a difference in concentration in one place compared to another. This is called what?
What is concentration gradient
100
During passive diffusion, energy is what
What is not required
100
Active transport requires energy in the form of what
What is ATP
100

Substance that is dissolved in a solution

What is solute

200
Allows only certain materials to go into and out of cell
What is selective permeability
200
During diffusion, molecules move from a _____ concentration to a ______ concentration
What is high to low concentration
200
What grabs molecules, changes shape, and flips across to the other side like a revolving door
What is carrier protein
200

During active transport molecules move from areas of _________ to _________ concentration

What is low to high

200

In this type of solution the solute concentration is greater inside the cell, so water rushes into the cell causing it to swell

What is hypotonic

300
The portion of the cell membrane that does not like water
What are hydrophobic tails
300
Diffusion continues until the concentration is equal in the space.
What is equilibrium
300
What creates a tunnel through which molecules can pass
What are channel proteins
300
Proton pumps use what kind of proteins to move molecules
What is integral proteins
300

This type of solution is ideal for plant cells

What is hypotonic

400
Cells maintain a stable environment
What is homeostasis
400
The movement of water molecules across a cell membrane
What is osmosis
400

In passive transport molecules move _______ the concentration gradient

What is along, down, or with

400

With the sodium potassium pump how many of each element is pumped in and out

What is 2 K+ in and 3 NA+ out.

400
Pressure exerted by the movement of water during osmosis
What is osmotic pressure
500

Molecules that cannot pass directly through the phospholipid bilayer may pass through these

What is carrier protein

500

This osmotic solution is ideal for animal cells

What is isotonic solution

500

Large molecule produced by photosynthesis that is helped by carrier proteins

What is glucose

500

Two types of bulk transport (active) of releasing things out of cells and the process of taking substances into cells using vesicles

What is endocytosis and exocytosis

500

Cell body shrinks and pulls away from the cell wall (plasmolysis) in this type of solution
