USING ENGLISH TO GIVE EVIDANCE

         Chemical reactions can happen anywhere around us, not just in the laboratory. Matter interacts to form new products through a process called chemical reactions or chemical changes. Every time we cook or are cleaning, it is also a chemical in action. Our bodies live and grow thanks to chemical reactions. There are reactions when we take drugs, light a match, and take a breath. Here are 10 examples of chemical reactions in everyday life. This is just a small example, because we see and experience hundreds of thousands or even more chemical reactions every day.

1.  Photosynthesis                                                                                                                 Photosynthesis is a process used by plants and other organisms to convert light energy, usually from the Sun, into a chemical energy that can then be liberated to fuel organism activity. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water. In most cases, oxygen is also produced as a waste product. Most plants, mostly algae, and cyanobacteria do photosynthesis, and these organisms are called photoautotrophs. Photosynthesis maintains atmospheric oxygen levels and supplies all organic compounds and most of the energy needed for life on Earth. Briefly, plants use a chemical reaction called photosynthesis to convert carbon dioxide and water into food (glucose) and oxygen. It is one of the most common daily chemical reactions and also one of the most important, because this is how plants produce food for themselves and animals and convert carbon dioxide into oxygen.  6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
2.             Metabolism In The Body
   Cells are the smallest unit of life, therefore cells can carry on life activities, including metabolism. Metabolism is the chemical processes that occur in the body of a living thing / cell. Metabolism is also called enzymatic reaction, because metabolism always occurs using enzyme catalyst. Cells are the smallest unit of life, therefore cells can carry on life activities, including metabolism. Metabolism is the chemical processes that occur in the body of a living thing / cell.Metabolism is also called enzymatic reaction, because metabolism always occurs using enzyme catalyst.Based on the process metabolism is divided into 2, namely:1. Anabolism / AsimilasI / Synthesis,Namely the complex molecular binding process using high energy. Example: photosynthesis (assimilation C)
                              Light energy6 CO2 + 6 H2O -----------> C6H1206 + 6 02
   Chlorophyll glucose (chemical energy)In chloroplast there is transformation of energy, that is from light energy as kinetic energy turns into chemical energy as potential energy, in the form of bond of organic compound on glucose. With the help of enzymes, the process is fast and efficient. When in a reaction requires energy in the form of heat reaction is called an endergonic reaction. Such a reaction is called an endothermic reaction.2. Catabolism (Assimilated),Namely the process of decomposition of substances to liberate chemical energy stored in the organic compound.Example:enzymeC6H12O6 + 6 O2 -----------> 6 CO2 + 6 H2O + 686 KKal. Chemical energyAs the molecules break down into smaller molecules, the release of energy creates heat energy. When a reaction is released by energy, its reaction is called an exergonic reaction. Such reactions are called exothermic reactions.
3. Benefits of Chemistry
   
   Branch of Chemistry
   Before really knowing the benefits of chemistry for life, it's good if we know chemistry further. Chemistry is divided into several parts, the parts will have and represent the benefits of different chemistry in each branch. The branch of chemistry among them is,
   
   Organic Chemistry. This field focuses the study on research on organic compounds (hydrocarbon compounds), such as alcohol, gasoline, diesel, and others.
   
   Inorganic Chemicals. This field focuses on studies on the study of inorganic compounds such as salts, minerals, and others.
   
   Biochemistry. This field deals with the biological sciences, especially regarding the nature and composition of the compound and the result of its change reaction. The compounds studied include carbohydrates, proteins, fats, vitamins, enzymes, hormones, and others.
