Which of these materials is not a major component of the plasma membrane?
This membrane is called the fluid mosaic model as it is a mixture of phospholipids, cholesterol, proteins and carbohydrates. It is mainly phospholipids. The proteins sort of float on the surface of the membrane like islands in the sea.Cholesterol is also found in the membrane. It prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity.
Plasma membrane What will be the orientation of plasma membranes main component?
Assuming the main component is phospholipis, the polar heads will be facing the aqueous solution, ie the extracellular environment and cytosol. The non-polar tails will be facing each other. This together creates a lipid bi-layer.
What is the main role for proteins?
Intrinsic proteins are the integral proteins inside the plasma membrane, or phospholipid bilayer, of a cell. The reason they are called intrinsic is because they cannot be released unless the membrane is disrupted.
What is main structural components of the wall of a plant?
Plant material is the main structural component of plants.
The main structural component of plant cell walls is?
cellulose
What componenet of the plasma membrane forms most of the cell's outer boundary?
The human cell has three principal parts which are the plasma membrane, cytoplasm, and the nucleus. The outer boundary is the plasma membrane.

Which function does the lipid bilayer component of the plasma membrane NOT provide for the cell?
The functions that the lipid bilayer component of the cell membrane does not provide for the cell are controls that exchange of mater and chemical information between one cell and adjacent cells or environment. The lipid bilayer provides an impermeable, self sealing membrane capable of dividing or fusing the cell without breaking.
Another name for plasma membrane?
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
What component of the plasma membrane forms most of the cell's outer boundary?
the phospholipids. by weight it is half protein and half lipid
What is main structural components of the wall of a plant?
Plant material is the main structural component of plants.
What is the main structural component of the body?
water
Cellulose is the main component of what?
Glucose .
What is the largest component of blood?
Plasma is the component that makes up over half of the blood, and the main ingredient in plasma is water.
The main structural component of plant cell walls is?
cellulose
