Front 1

Phospholipids

Back 1

Lipids consisting of a glycerol, two fatty acids, and a polar phosphate head.

Hint 1

PHOSPHO - phosphorous
LIPID - oil
PHOSPHOLIPID - phosphorous + oil
The membrane consisted of many phospholipids, each one with a non polar tail pointing into the membrane's center.

Front 2

Phospholipid Bilayer

Back 2

The bilayer in cell membranes, which is semipermeable and consists of many phospholipids.

Hint 2

The membrane of a human's cells.
The phospholipid bilayer was selectively permeable, allowing only specific molecules to pass through.

Front 3

Polarity

Back 3

The tendency of a molecule to have opposite ends with opposites charges.

Hint 3

H2O, with the oxygen atom positive and the hydrogen atoms negative.

Front 4

Transport proteins

Back 4

Special proteins, embedded in the membrane, which help charged molecules and small polar molecules into the cell.

Hint 4

Hemoglobin is the transport protein of oxygen.

Front 5

Selective permeability

Back 5

The specific regulation of membranes on the exchange of materials.

Hint 5

Ex. A membrane will allow water through, but not ions.
The selective permeability would not allow glucose through the membrane without a transport protein.

Front 6

Glycoproteins/glycolipids

Back 6

Proteins/lipids that have a sugar attached to them. They are the receivers of chemical messages between cells.

Hint 6

Ganglioside in the gray matter of the brain.
The glycoproteins received messages from the other cell.
