The Biology Definition

The Biology DefinitionThe Biological Chemistry Definition is the relationship between biological matter and the processes that produce or support its function. In simple terms, it is the means by which an organism receives nourishment, grows, reproduces and dies.Biological matter is produced through an organism's metabolism (i.e. the chemical reactions that cause this to happen).Biological matter is produced from chemical reactions between these energy sources - oxygen and the molecular nitrogen. Organic molecules that contain one carbon atom are called organic compounds, such as proteins, DNA, and chlorophyll.Living systems consist of billions of living biological molecules, called cells. These molecules carry out many different functions within the body. Each cell is highly specialized for a specific function - for example, blood cells carry oxygen, white blood cells help fight infection, red blood cells give us a lot of iron to use for energy, and so on.The cellular structure that is formed from the division of cells is called a 'cell' (in the way that a house is a structure that contains bricks), but it is really a group of cells called a 'population.' The whole population is usually microscopic in size, but it can grow and become very large if it is in contact with another population.The cell also has other biological components. For example, a protein called RNA carries out genetic instructions, and ribosomes can produce almost all of the enzymes necessary for life, including enzymes needed to make amino acids, and fatty acids.The properties of biological molecules are relatively easy to describe, but it is often difficult to figure out what they mean in the context of a system. For example, I am talking about the case of a complex protein that performs a specific function.To explain this in general terms, it is best to talk about what chemical reactions are, and why they happen. If we could go back in time and watch the reaction of one organic molecule i n some process of protein synthesis, then we could understand the complete process. But this is usually not possible - we need to be able to observe actual reactions in a more or less exact fashion, to be able to explain their nature.
