The cell is the basic unit of the human body where each organ is gregasi / unification of the various cells that are united to one another by endorsement interselluler structures. Each type of cell is devoted to perform a particular function. For example, the number of red blood cells 25 trillion serves to carry oxygen from the lungs to the tissues.
In addition to red blood cells there are about 75 trillion cells that make up the human body else, so that the number of human cells in about 100 trillion cells. Although many cells are different from one another, but generally the whole cell sifar have basic properties that are similar to each other, for example:
1). oxygen is bound to the carbohydrate, fat or protein in each cell to release energy
2). common mechanism to change food into energy
3). each cell release final results to the fluid surrounding the reaction
4). almost all cells have the ability to conduct reproductive and if a particular cell gets damaged then other similar cells will regenerate In general, the cells that make up the human body has a basic structure consisting of a cell membrane, protoplasm and the cell nucleus (nucleus).
All three have a chemical composition consisting of water, electrolytes, proteins, fats and carbohydrates.
a. Water The main fluid medium of the cell is water, which is present in 70-85% concentration. Many chemicals cell soluble in water, while others are in the form of suspension or membranous
b. Electrolyte The most important of the cell electrolyte is Potassium, Magnesium, Phosphate, Bicarbonate, Sodium, Chloride and Calcium. Inorganic electrolyte provides material for cellular reactions and mechanisms involved in the control of cell
c. Protein Plays an important role in virtually all physiological processes and can be summarized as the following:
1. Enzymatic Process
2. The process of transport and storage
3. The process of movement
4. Mechanical function
5. Immunological processes
6. Originator and conductor of impulses in nerve cells
7. Regulate the growth and regeneration
d. Fat Fatty acids are a component of the cell membrane is a long hydrocarbon chain, while the fatty acids stored in the cell is triacylglycerol, a highly hydrophobic molecule. Because triacylglycerol molecule is not soluble in water / saline solution it will form lipid droplets in fat cells (adipose cells), which is a source of energy. Fatty molecules that make up cell membranes have hydroxyl groups (phospholipids and cholesterol) that can bind to the water, while the other hydrophobic groups (not tied to water) so-called amfifatik.
e. Carbohydrate A carbohydrate composed of atoms C, H, and O. Carbohydrates that have 5 C atoms are called pentoses, six C atoms called hexosa are carbohydrates that are essential for cell function. Carbohydrates are made up of many units called polysaccharides. Polysaccharides serve as a backup energy source and as components that make up the outer surface of the cell membrane.
Carbohydrates that bind to proteins (glycoproteins) and that bind to fats (glycolipids) is an important structure of the cell membrane. Besides structuring glycolipids and glycoproteins blood group antigens that can induce an immunological reaction. Similarly, other living beings, the same chemical constituent cells. Constituent chemical compound called a blastema cells. Protoplasm is a complex substance. Most of the protoplasm consist of water. nevertheless characterize the protein structure. Organic compounds in the protoplasm form of carbohydrates, fats, proteins and nucleic acids.
