Description

Membrane transport is a collection of mechanisms in cellular biology that regulate the movement of solute molecules such as ions and small molecules through biological membranes, which are lipid bilayers with proteins embedded in them. The selective membrane permeability is a characteristic of biological membranes that allows to separating substances of different chemical environment it is responsible for the control of movement through the membrane and they can be permeable to certain substances but not others.

The mobility of these solute molecules across the membrane is affected by membrane transport proteins, which are specialized in the transport of specific molecules to various degrees. Because of the diversity and human biology of different cells are highly related to their ability to attract various external elements, it is hypothesized that there are a group of specialized transport proteins for each cell type and physiological stage.

This differential expression is regulated by variability transcription of the genes that encode for these proteins and transformation. For example, through genetic-molecular mechanisms, but also on the level of cell biology. The development of these proteins can be activated by cell signaling pathways, biochemical mechanisms will be located in cytoplasmic vesicles.

Types of Transportation

Passive and active diffusion

The passive diffusion is a natural phenomenon that increases a machine's electron density whereas reducing its free electricity. The characteristics of a transport substance and the nature of the cell membrane influence the transport process. A natural phospholipid membrane's diffusion velocity is determined by the following factors: concentration gradient, surface charge, size, and cost (if the molecule has a positive charge), and temperature.

Co-transportation and active transportation

Active transport involves the movement of a solute it against a concentration or electrochemical variation, the transport of proteins involved metabolic energy consumption, Adenosine triphosphate, inside the procedure. In active transport, the energy provider is hydrolyzed directly in order to transport the solute, when the transport proteins are ATP enzymes. When the power generation provider's hydrogenation is a variable, as in secondary active transport, the energy stored in an electrochemical variance has been used. For example, in cotransport, the variance of some solutes is used to transport a target compound against its variation, causing the solute difference to dissipate. Although it might appear that no energy is used in this illustration, hydrolysis of the energy provider is required to establish the variance of the solute transmitted along with the particular compound. The difference of the cotransported solute will be generated by the use of specific proteins is known as biochemical pumps.

Secondary active transporter proteins

Secondary active transporter proteins transport two molecules at the same time. They are differentiated by the orientation of the two molecules: Both can be assumed as co-transporters.

Antiporter: Antiporter is also known as separator or countertransporter. Continues to move a molecule against its gradient while removes one or more ions along it and molecules are moving in opposite directions.

Symporter: It is a chemical compound that moves against its gradient while removing one or more ions along its difference and the molecules are moving in the same direction.

Pumps

A pump is a protein that catalyzes the hydrolysis Adenosine triphosphate to transport a specific solute across a membrane, it generating electrochemical gradient membrane permeability in the procedure. This gradient is informative because it can be used to predict the state of the cell by using variables like the Osmotic ability. The gradient is important in membrane transport because it contributes to decrease the structure of osmotic pressure in the co-transport of substances against their gradient.

Membrane selectivity

The main function of membrane transports through a biological membrane its selectivity and subsequent behavior as a barrier for certain substances, the physiology of the phenomenon has been extensively studied. Membrane selectivity study has typically divided into two categories: Electrolyte selectivity and Nonelectrolyte selectivity.
