Bio Membrane and Function

Method cells use to take in macromolecules

Endocytosis

Method cells use to take in monomers

Facilitated Diffusion & Active Transport

Method cells use to take in water molecules

Osmosis/Facilitated Diffusion

Ions needed by the cell

Sodium, potassium, calcium, chloride

Method cells use to take in small ions

Active Transport, (because of charge)

Nonpolar gas molecules needed by the cell

Oxygen, Carbon Dioxide

Method cells use to take in gas molecules

Diffusion

Active transport into cell

Endocytosis

Active transport out of cell

Exocytosis

Lipids with carbohydrate chains that serve as cell recognition markers

Glycolipid

Proteins with carbohydrate chains that can serve as cell recognition markers and can help neighboring cells interact or stick to each other

Glycoprotein

Proteins that can send to nearby cells or receive signals from outside their cell. They can also serve as anchors for other proteins inside the cell

Membrane Protein

Proteins that help carry substances across the membrane or allow molecules to pass through a channel

Transport/Channel Proteins

Lipids with hydrophobic tails and hydrophilic heads that form two layers in the membrane

Phospholipid

A hydrophobic lipid molecule that changes the fluidity of the membrane

Cholesterol

Long protein chains that help the cell hold its shape. Organelles and other large molecules can travel along these chains like super highways in the cell.

Cytoskeleton Filaments

Middle/Inside

Integral

Side, Partially in bilayer

Peripheral

Resting on surface

Surface

If a protein runs through the phospholipid bilayer completely, which part is hydrophobic?

The part inside
