Metabolism describes the total chemical changes that occur inside a cell. Chemical reactions must occur inside the cell for cells to maintain their structure and function. These chemical reactions occur by using the chemical energy found in an ATP molecule. There are two cellular metabolic processes known as anabolism and catabolism. Anabolism is a process of building up larger molecules from combining smaller molecules. Catabolism is the process of breaking down larger molecules into smaller molecules.
Glycolysis is the aerobic and sometimes anaerobic breakdown of glucose molecules. The first step in glycolysis occurs in the cytoplasm of the cell. As a result of the breaking down of an ATP molecule into ADP and PO4, energy is released that allows for the phosphate to be added to the glucose. The glucose phosphate quickly changes to another sugar phosphate(C6) called fructose phosphate. ATP is then broken down again into ADP and PO4 to release energy to ass a phosphate to the fructose phosphate, thus creating fructose diphosphate. In order for ATP to be created, two ATP will be used in the...
