This type of transport occurs without energy and particles flow from

high to low concentration.

Passive Transport

Particles flow from high to low

concentration with the help of membrane

proteins.

Facilitated Diffusion

This type of transport requires energy because the particles flow from

low to high concentrations.

Active Transport

Engulfing of large particles or

liquids from outside the cell.

Endocytosis

Release of large particles or liquids from

inside the cell.

Exocytosis

The name of the lipids that are

classified as fats and oils.

Triglycerides

The 3 carbon chain that attaches to long

chains of hydrocarbons.

Glycerol

These long chains of hydrocarbons are major components

in lipids.

Fatty Acid tails

These fatty acid tails contain at least

one carbon to carbon double bond

Unsaturated Fat

These types of fats are found in products such as butter, milk,

and shortening.

Saturated Fat

The area of the cell membrane

that is considered hydrophilic.

Polar Phosphate

Heads

Certain types of lipids are synthesized into

molecules such as cholesterol, sex

hormones, birth control molecules, and cortisone.

Steroids

The 3 fatty acid tails bond to the glycerol in

a lipid through this process.

Dehydration Synthesis

This type of cell membrane transport

occurs when only large particles are engulfed from outside the cell.

Phagocytosis

Glycoproteins contains this macromolecule that

sticks out from the surface of the membrane.

carbohydrate

The boundary between the cell

and the environment.

Cell Membrane

By bringing in nutrients such as glucose, amino acids, and

lipids, and removing waste from the cell, the cell membrane

helps maintain this.

Homeostasis

This describes the cell membrane’s

ability to let some molecules in and keep others out.

Selective Permeability

This model describes the membrane as

flexible; the components move and shift around but make

up a pattern.

Fluid Mosaic Model

These proteins are incorporated in the

cell membrane.

Integral Proteins

These structures make up the general form of the cell

membrane, with their phosphate heads and fatty

acid tails.

Phospholipid

This molecule stabilizes the

phospholips and keeps them from sticking together.

Cholesterol

This protein is used to identify the cell. (Cell to Cell recognition)

Glycoprotein

This protein transports or carries

ions into the cell.

Carrier Protein

This cell membrane component has binding sites for hormones to bind to and cause a reaction to occur.

Receptor Protein

The net movement of particles from areas

of high concentration to low concentration.

Diffusion

Distilled water is an example of this type

of solution.

Hypotonic

Particles may continue to move but no change in concentration occurs

because this has occurred.

Equilibrium

The diffusion of water across a

selectively permeable membrane.

Osmosis

The solution of salt water in the ocean is an example of this type of

solution.

Hypertonic

Tonic WaterTonic Water

Give examples of the three different types of solutions and explain how water molecules would move if a cell

was placed in each one.
