WebGlucose Phosphorylation. Catabolism is the initial step of the phosphorylation of sugars. It occurs when a cell allows the accumulation of sugar. It plays a vital role in sugar mechanisms. Before metabolism, the first step is the conversion of sugar into glucose. The above reaction illustrates the conversion of D-Glucose to D-glucose 6-phosphate. WebEpigenetics involves heritable changes in gene function, without changes to the base sequence of DNA Changes to the epigenome are caused by changes in the environment Smoking, stress, exercise and diet can cause epigenetic changes Internal signalling from the body's own cells can also cause modifications to occur
