Document Summary
The human body is a vast system of cells that work together. Eating is how we provide the basic chemical and energy needs for the cells. Metabolism: includes all chemical and physical processes we find in living cells. Catabolic process: the larger molecules are broken down into smaller ones, resulting in the release of energy. Anabolic process: those that require energy to build larger molecules from smaller ones. Note: it is about the energy in the food that is what an organism requires most of all. A key anabolic process is dehydration synthesis: in which two molecules are bonded to one another when a water molecule is removed during the reaction. We have already encountered this chemical process in the form of poly saccharides (unit one: understanding food at the molecular level part 2) When carbohydrates ae eaten perhaps in the form of grain the large molecules.
