Q:What is the use of inorganic salts and organic salts?
The organics are compounds containing carbon, and the inorganic salts are salts containing no carbon. For example, we usually eat sugar is organic matter, salt is inorganic salt.
Q:What are the physiological functions of inorganic salts
Maintain the life of cells and organisms
Q:Can basal salt cause disease or illness?
the web page (below) discusses: Basal Salt Mixtures The use of balanced salt solution (BSS) in cell and tissue culture is generally attributed to early workers in the field. In 1885, Sydney Ringer developed a solution of inorganic salts designed to maintain contractility of mammalian heart tissue. A less specific salt solution was designed by Tyrode for use in work with primary mammalian cells. Tyrode's salt solution became the accepted fluid for diluting protein components of media of natural origin. Since that time, many other balanced salt solutions have been developed for use in cell and tissue culture. The current role of balanced salt solution in cell culture is multi-faceted and can be divided into four principle functions. see web page for extensive discussion on the good things about it
Q:Where are the parts of the bryophyte absorb water and inorganic salts?
Moss moss moss, moss Gang, moss root through the fake root absorption, that is, the use of cell penetration technology, moss Gang has evolved out of the root, so you can directly through the relatively low roots to absorb Oh
Q:Does the urine and urine contain inorganic salts? Anxious
When the blood flows through the glomerular, in addition to blood cells and macromolecules of protein, the plasma part of the water, inorganic salts, glucose and urea and other substances, can be filtered through the glomeruli into the renal capsule, the formation of urine ; When the original urine through the renal tubular, which is useful for the human body substances, including most of the water, all the glucose and part of the inorganic salt, reabsorbed by the renal tubules, and into the capillaries outside the renal tube, To the blood; in the renal tubular reabsorption at the same time, renal tubular epithelial cells will produce substances (such as ammonia) secretion into the renal tubular bureaucratic, and the original urine of other waste, such as urea, part of the water and inorganic Salt, etc. from the renal tubular effusion, the formation of urine. Therefore, plasma, urine and urine are contained in the material is water, inorganic salts, urea.
Q:What is the risk of low inorganic salt?
Phosphorus into the body of phosphorus containing 750-800mg about 1% of body weight, mineral weight of 1/4. Of which 87.6% in the form of hydroxyapatite bone salt stored in the bones and teeth, 10% with protein, fat, sugar and other organic matter combined constitute soft tissue, the rest distributed in the muscle, skin, nerve tissue and other tissues and membranes Of the ingredients. Function Phosphorus is present in every cell of the human body, which is indispensable for bone growth, tooth development, renal function and nerve conduction. Phosphorus is a component of nucleic acids, phospholipids and certain enzymes, which promotes growth and tissue repair. It helps carbohydrate fat and protein utilization, regulates glycogen breakdown, and participates in energy metabolism. Phospholipids are the major components of the cell membrane, which are related to the permeability of the membrane. Phosphate can regulate the metabolism of vitamin D, to maintain the stability of calcium within the environment. Lack of disease  phosphorus deficiency when the mental confusion, cranial nerve palsy, transport disorders, muscle weakness, hypothyroidism, anorexia, joint stiffness, abnormal blood, urinary calcium increased. Typical cases  hyperphosphatemia, renal dysfunction, or hypoparathyroidism and hypothyroidism and other endocrine diseases can also occur. Too many symptoms  nerve excitement, tetany and convulsions. The physiological requirement of phosphorus is 12.3mg / kg / d. Calcium / phosphorus ratio in the 2: 1-1: 2 appropriate range. Food sources  food in the meat, fish, milk, beans and hard shells and other phosphorus more.
Q:The human body does not intake of minerals can be? Lack of minerals on the human body what kind of harm?
Body weight: 96% is organic matter and moisture, 4% for the inorganic elements of the body about 50 kinds of minerals, in these inorganic elements, has been found in about 20 elements constitute the body tissue, to maintain physiological function, Biochemical metabolism necessary, in addition to C, H, O, N mainly in the form of organic compounds, the rest are known as inorganic salts or minerals can be divided into constant elements and trace elements two categories.
Q:Does the plant roots absorb inorganic salt ions must be active
Plants absorb inorganic salts and do not necessarily absorb water. Plants absorb moisture and absorb inorganic salts are two relatively independent processes. Plants absorb moisture through the infiltration of root cells to absorb water, the process is essentially free of water diffusion process, neither the carrier nor the need for energy; and plant absorption of inorganic salts is carried out by means of active transport, This process requires the carrier and consumes the energy generated by cell metabolism. Of course, plant water absorption and absorption of inorganic salts are a certain association, inorganic salts to be dissolved in water to be absorbed, and inorganic salt ions in the transport of plants can not be separated from water.
Q:Inorganic salts play an important role in maintaining the life activities of living organisms. It is mainly in the form of living organisms.
Inorganic salts are mineral nutrients present in the body and in the food. Most inorganic salts in the cells are present in the form of ions, consisting of organic matter and inorganic compounds.
Q:what is leading inorganic salt of nervous system?
The sodium-potassium pump is most important in controlling the working of neurotransmitters. Calcium ion is also generated in voltage gated Ca++ channel, and Magnesium is necessary for metabolic functions. But Sodium is one of the most important inorganic component in our body. Of course Potassium is also as important. But, if you have ever seen the back of all food products there is a special part showing amount of Sodium in it...even Snacks.. :)
