The structure and function of the membrane!

It is a membrane that envelops the cytoplasm of the cells of every body.

1. Chemical composition:
Mainly protein, lipid, glutamic and some other substances.
Protein: There are many proteins but only two proteins that make up the cell membrane are filaments and membrane proteins that act as membranes and fillers.
Lipid: There are two types of lipids involved in the production of membrane: phospholipids form phosphorous acids and sulfuric acid.
Glucose: Mainly short sections of dextrin, which are attached to proteins through the membrane creating gluten-protein.
Enzyme hydrolysis, carrier, receptor, pecmerase, H2O.
2. Structure:
Membranes are complex and complex. There are many models presenting the structure of the membrane.
Simple membrane structures (Daniel – Dacson): The membrane contains a double layer of lipid in the middle, two inner and outer layers of protein, on the membrane with tubes lined with spots or small pores.
Animated Membranes: The mosaic model is widely accepted, explaining the structural nature of the membrane. Film mosaic including:
– The two lips: the basic layer, which constantly forms the frame for the membrane.
The cell membrane consists of protein and fiber proteins. Some are called cell membrane proteins, which run straight through the cell membrane and have both intracellular and extracellular tissue. The other protein called a fixed protein in a double layer or just attached to the outer surface of the membrane, receives a signal that passes to the protein of the hole. Cloudy protein has important functions in the metabolism of membranes.
Characteristics of membrane:
Flexible:
Liquid mosaic (molar molecules: phospholipid molecules and non-stop proteins).
The non-dispersible phospholipids molecules that they just stack together and the horizontal diffusion of these phospholipids molecules make the film direction.
Cholesterol is mixed with phospholipids that break down the wedge to make the film thin and loose.
Selectivity of tuberculosis:
There are two structural features:
The more polar molecules dissolve in the lipid membrane, the more readily absorbed.
Transmission proteins allow the transfer of membranes of different water stimuli in different directions and speeds.
Biological Equivalence of Biofilm:
+ biological balance of biofilms.
Filmmaker is not symmetrical.
– Membrane formation: Membrane is made only from the membrane.
Tb membrane is the strongest multiplication before dividing the cells by doubling the membrane of TB to Tb.
TB membranes are often contracted by concave to create waste bags and bags.
General function of membrane
Enclosed by cells, the boundary between cells and the environment
– A fence that allows the material to pass through the membrane in two passive and active modes – Communicate by chemical and physical signals.
– Information processing
Identification: Identify familiar, exotic, enemies
+ Stimulates or inhibits the contact between cells, the cell with the substrate. Substrates for enzymes catalyze biological reactions on cell membranes, toxins, viruses, and resistance to structures on the cell membrane.
. Function:
Cell protection: protection of physical and chemical efficiency, mainly protect the chemical effects.
Transmission of substances through the membrane: regulation of the transport of material into and out of cells, made by two mechanisms is the mechanism of action and the mechanism of passivity.
– Passive mechanism: The nature of the mechanism is to transport substances through the membrane through osmosis diffusion mechanism. This mechanism does not consume the energy of the cell.
– Mechanism of action: Depending on the needs of the cell, transport activity represents the living nature of the cell and requires energy.
Essence: Due to the activity of the cell, especially the “living nature” of the cell membrane and the involvement of the components and components due to metabolism.
Mechanism: Thanks to carriers, receptors, trains; Membranes of membranes help to insert ion, large and insoluble in the membrane; Glucose anabolicism is the most important source of energy in the cell.
Transmission through membranes: Complex organic substances are hydrolysed into simple organic substances and transported through the membrane by enzymes attached to the cell membrane.
The transmission of genetic information from one cell to another, including prolonged endocrine disorders, transmission, and aphasia.
* Enterobacteriaceae and exocytosis: The process of actively collecting large molecules does not pass through the cell membrane.
