The biological membrane is described as fluid because the phospholipid molecules and proteins can move within the lateral plane of the bilayer.

Cholesterol is present in the bilayer because it is a non-polar, hydrophobic molecule.

The lipid bilayer is so called because it is composed of both lipids and proteins.

The carbohydrate chains of glycolipids and glycoproteins are found on the intracellular surface of the membrane.

The lipid bilayer of biological membranes is formed by phospholipid molecules with hydrophilic tailgroups and hydrophobic headgroups.

Bind substrates and then undergo conformational change to transport substrates across membrane

The structures that allow cells to adhere together to form a tissue

The hydrophilic ends of the lipid bilayer, facing the aqueous environment outside the cell

The coat of glycolipids and glycoproteins across the outer cell membrane surface

Integral membrane proteins that form aqueous pores to allow movement of substances across the membrane

Are membrane-associated proteins that are associated but not inserted into the cell membrane

Are integral proteins found either in the inner or the outer leaflet of the lipid bilayer of the cell membrane

Are carrier proteins that bind substrate for transport across the membrane or channel proteins that form aqueous pores through the membrane

Are channel proteins that bind the substrate that needs to be transported across the membrane

Are carrier proteins that make up the secretory vesicles used for extrusion of products from the Golgi apparatus

It decreases the permeability of the membrane

It increases the permeability of the membrane

It links together the membrane without the need for covalent bonds

It allows the phospholipids of the membrane to easily move laterally

It links cells to withstand stress and stretching

Its lipid composition, the type of glycolipids and the number of integral membrane proteins.

Its lipid composition, the amount of cholesterol it contains, and the temperature

The surface area and lipid solubility only.

Lipid solubility, lipid composition, lipid type.

The temperature, the surface area and the lipid dissolvability of the membrane

They arrange themselves so the polar ends face the water and the non-polar tails face away from the water.

The water causes the polar tails to dissociate from the non-polar heads.

The cholesterol molecule inserts itself into the non-polar tails of lipids.

The water causes the polar heads to dissociate from the non-polar tails.

The lipid forms a membranous micelle.
