Cell Membrane Diagram And Functions

The major constituents of the plasma membrane are highly charged molecules of carbohydrates proteins and nucleic acids.

Cell membrane diagram and functions. Diagram of Cell Membrane or Plasma Membrane. The cell membrane plays an important role in regulating the entry and exit of specific substances within the cell. We all remember that the human body is amazingly intricate and a.

This organelle is also referred to as plasma membrane. Also called the cell membrane this structure is semi-porous and allows certain molecules in and out of the cell. BBC Bitesize GCSE Biology Single Science Variety of.

Major Components of the Cell Membrane. Diagram of the human cell illustrating the different parts of the cell. It is the outermost covering of animal cells.

Protecting the integrity of the interior cell. Thin barrier separating inside of cell cytoplasm from outside environment Function. In this regard a direct relationship exists between the size and shape of a cell and its intended function.

Images obtained through electron micrography reveal the bilayer structure of cell membranes. The cell membrane has lipids and glycoproteins that function mainly as receptors and channels that allow specific molecules ions nutrients wastes and metabolic products to pass between organelles and also between the cell and the outside environment. The cell membrane also called the plasma membrane is found in all cells and separates the interior of the cell from the outside environment.

The main function of the plasma membrane is to protect the cell from its surrounding environment. The plasma membrane comprises Phospholipids Cholesterol Proteins and Carbohydrates. The fluid nature of the membrane owes itself to the configuration of the fatty acid tails the presence of cholesterol embedded in the membrane in animal cells and the mosaic nature of the proteins and protein-carbohydrate complexes which are not firmly fixed in place.
