Document Summary
Fructose biphosphate: the enzyme that catalyzes the conversion of fructose 1,6-bisphophate to fructose- Carbohydrates are an important source of energy and reducing power for the cell. Glucose is absorbed from the digestive tract via glucose speci c transport proteins into the blood. Inside the cell glucose is converted to glucose 6-phosphate. Glucose is oxidized by glycolysis to provide energy to the cell (in your muscle cells and sometimes in your liver). Glucose-1- phosphate is added to the glycogen chain in a two step reaction that involves the net hydrolysis of utp to udp and pi. Glycogen (n residues) + g1p + utp --> glycogen (n+1 residues) + udp+ 2pi. Not sure why glycogen is going to glycogen let me know if you know https://uwoca-my. sharepoint. com/personal/akalluma_uwo_ca/_layouts/15/wopiframe. aspx?sourcedoc={5e62ed6a-49ad-486b-a23a-ea4b3ec5cbfc}& l Hydrolysis of utp to udp and pi is energetically similar to hydrolysis of atp to adp and pi. Ntp"s are readily interconverted by the enzyme nucleoside diphosphate kinase:
