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 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.
