What is the role that the chlorine plays in the human body?
A necessary part of human biochemisty is table salt, sodium chloride, which of course is a compound of sodium and chlorine. It is the sodium which the body uses, but the chlorine gives us a usable ionized form of sodium.

How many sugar molecules are in monosaccharide?
Monosaccharides are classified based on their backbone of carbon (C) atoms.In fact , they exist in five types and they are :1. Trioses have three carbon atoms, 2. tetroses four,3. pentoses five, 4.hexoses six, and 5.heptoses seven
What is the relevance of biochemistry in conservation biology?
An appreciation of biochemistry is essential to understanding a multitude of environmental factors. Take deforestation and desertfication for example... For a long time it has been thought that mere over-abundance of livestock lead to desertfication. When herds were reduced or removed, desertfication increased! The explanation for this is apparent to one who understands biochemisty: Animal feces and urine contribute substantial carbon and nitrogen loads to the soal. Complex organic matter with multiple hydrophylic compounds can hold moisture in the soal and can alter the microbial flora to one that promotes processes favorable to plant root development. All ecosystems involve interactions in water, soil and air - to understand the ecology of these systems you need to understand the contributing elements.
What are the medical uses of radioactive substances?
AnswerA few important uses of radio-isotopes (usually called radionuclides) are: Radio-isotopes are widely used in medicine, as tracers that show up on X-ray film, and sometimes to destroy cancerous growths.They are also used widely in industry. The radiation emitted by different radio-isotopes can be used for rapid, highly accurate measurement of material thickness, including the thickness of platings or coatings. The purity or composition of materials can be established by means of radio-isotopes. Radio-isotopes are used as gamma ray sources to irradiate and sterilize materials.In agriculture, radio-isotope tracers can be used to check for proper distribution of insecticides.Radio-isotopes are used to detect pipeline leaks, and to trace underground water.Naturally occurring radio-isotopes can be detected in forensic science, to assist in solving crimes.Naturally occurring radio-isotopes are also used by archaeologists and related specialists to help establish the authenticity and age of specimens.Naturally occurring radio-isotopes are often used by geologists to establish the ages of rocks.A link is provided to the Wikipedia article on the uses of radionuclides.
What blood cells bring oxygen to cells?
That would be the Respiratory System. The respiratory system is responsible for the gas exchange in the cells of your body. When you inhale (or breathe in), air passes through your nose, down your windpipe, and into two tubes called the bronchial tubes. These tubes lead into your lungs. The tubes branch many times, like a tree, so that your lungs are filled with tiny tubes. The smallest tubes can only be seen with a very strong microscope. At the ends of these tubes are air sacs. Air is moved from the air sacs into the cells of the body by diffusion. This is the movement of a substance from an area with a lot of that substance to an area with less of the substance. When the oxygen-poor cells arrive in the lungs from the heart, the oxygen moves into the cells. The CO2 (carbon dioxide), on the other hand, is more concentrated in the cells, so it moves out of the cells, and into the air sacs. When you exhale (or breathe out), the CO2 leaves your body by the same path by which the oxygen entered. Breathing is only a part of voluntary movement. Part of the reason that you breathe is involuntary. It is caused by the movement of muscles called the diaphragm. This is a sheet of muscles beneath your lungs. When the diaphragm moves downward, it increases the space around the lungs. When the diaphragm moves up, it decreases the space around your lungs, and the air rushes out.
What is the history of biochemistry?
Originally, it was generally believed that life was not subject to the laws of science the way non-life was. It was thought that only living beings could produce the molecules of life (from other, previously existing biomolecules). Then, in 1828, Friedrich Wöhler published a paper on the synthesis of urea, proving that organic compounds can be created artificially.[1][2] The dawn of biochemistry may have been the discovery of the first enzyme, diastase (today called amylase), in 1833 by Anselme Payen. Eduard Buchner contributed the first demonstration of a complex biochemical process outside of a cell in 1896: alcoholic fermentation in cell extracts of yeast. Although the term "biochemistry" seems to have been first used in 1882, it is generally accepted that the formal coinage of biochemistry occurred in 1903 by Carl Neuberg, a German chemist. Previously, this area would have been referred to as physiological chemistry. Since then, biochemistry has advanced, especially since the mid-20th century, with the development of new techniques such as chromatography, X-ray diffraction, NMR spectroscopy, radioisotopic labeling, electron microscopy and molecular dynamics simulations. These techniques allowed for the discovery and detailed analysis of many molecules and metabolic pathways of the cell, such as glycolysis and the Krebs cycle (citric acid cycle). Another significant historic event in biochemistry is the discovery of the gene and its role in the transfer of information in the cell. This part of biochemistry is often called molecular biology. In the 1950s, James D. Watson, Francis Crick, Rosalind Franklin, and Maurice Wilkins were instrumental in solving DNA structure and suggesting its relationship with genetic transfer of information. In 1958, George Beadle and Edward Tatum received the Nobel Prize for work in fungi showing that one gene produces one enzyme. In 1988, Colin Pitchfork was the first person convicted of murder with DNA evidence, which led to growth of forensic science. More recently, Andrew Z. Fire and Craig C. Mello received the 2006 Nobel Prize for discovering the role of RNA interference (RNAi), in the silencing of gene expression. Today, there are three main types of biochemistry as established by Michael E. Sugar. Plant biochemistry involves the study of the biochemistry of autotrophic organisms such as photosynthesis and other plant specific biochemical processes. General biochemistry encompasses both plant and animal biochemistry. Human/medical/medicinal biochemistry focuses on the biochemistry of humans and medical illnesses.
