Dear Friend,
My biology teacher, Mrs. Anderson, asked me to send you a note about the importance of chemistry in biology. Chemistry is an important part of biology. Modern biology overlaps with chemistry in explaining the structure and function of all cellular processes at the molecular level.  Chemical principles are important in modern cell biology because all living cells are made up of chemicals and many chemical processes occur in various living organisms. In biology you learn about living organisms and their composition. Organisms are alive because of chemistry. Chemistry is the one science in which all the other sciences are based. No matter what you are studying in biology, be it plants, animals, microbiology, etc., in order to fully understand it, you need to be able to understand the chemical reactions that need to take place in order for whatever organism you are studying to have life. Life is sustained through chemical reactions. Chemical reactions are important to all levels of biology. An example of this is when we eat something with sugar in it; the cells in our body chemically break down the sugar and turn it into energy, which is used to do things such as make our muscles move. Also, humans are supposed to take in 12 minerals (elements) (calcium, iron, phosphorous, iodine, magnesium, zinc, selenium, copper, manganese, chromium, molybdenum and chloride) a day as well. In total some 60 chemical elements have been found in the human body alone. These chemical elements are needed to continue bodily processes like breathing, digesting food, and thinking. Chemistry also determines how the organism looks, acts and functions. DNA, the instructions that tell the cells of an organism what to do, are part of biochemistry. DNA is made up of hydrogen, oxygen, nitrogen, carbon and phosphorus. These elements link together to form a strand of DNA or RNA. The cell is then formed around the blueprints laid out by the DNA this is the part where...
