7.3 Cell Membrane ID and Function Diagram | Quizlet

Phospholipid

A molecule that is a constituent of the inner bilayer of biological membranes, having a polar, hydrophilic head and a nonpolar, hydrophobic tail.

Phosphate Group- hydrophillic

water loving head

Lipid tail- hydrophobic

water hating tail

Glycolipid

a lipid with one or more covalently attached carbohydrates

Integral Transport Protein

large protein used to transfer large particles across the cell membrane

Carbohydrate Chain

substance on the plasma membrane helps identify chemical signals from outside the cell

Peripheral Protein

On the surface of the cell membrane. Some act as receptors, some as enzymes, catalyzing the reaction and since many are cytoskeletons, they give a cell its shape, offers support, and facilitates movement through three main components: micro filaments, intermediate filaments, and micro tubules

Cholesterol

A lipid that forms an essential component of cell membranes, allows flexibility

Lipid bilayer: 7-10 nanometers

width of the cell membrane

Glycoprotein

Protein (macromolecule) that holds the carbohydrate chain in place
