Metabolism is the set of life-sustaining chemical transformations within the cells of living organisms. These enzyme-catalysed reactions allow organisms to grow and reproduce, maintain their structures and respond to their environments. The word metabolism also relates to all chemical reactions that occur in living organisms, including digestion and the transport of substances into and between different cells, in which case the set of reactions within the cells is called intermediary metabolism or intermediate metabolism.
What Is Metabolism? Metabolism encompasses all of the chemical processes that occur within the cells of a living organism, in order to sustain life. There are many factors that influence metabolism – some that we can control, most that we cannot. Metabolism can be split in to 2 categories – anabolism and catabolism. Catabolism: This is the breakdown of organic substrates, for example, carbohydrate is broken down to glucose, protein breaks in to … [Read more...]
