Before sitting down you ate a bunch of sugar cookies and drank a soda (not diet!). Explain the effect of this meal on liver glycogen metabolism. Make sure to include relevant hormones and enzymes.
Liver can only store certain amount of glucose (sugar), so the rest can accumulate as fat in the organ. If any one exceed the amount of sugar it turns into fatty acids and thats way fat get deposits in the liver. That can lead to nonalcoholic fatty liver disease a condition when your body contain more fat than it can metabolize, causing it to accumulate in the liver cell.
Glycogen degradation and synthesis are biochemical processes .Glycogen degradation consists of three steps : (1) the release of glucose -1 phosphate from glycogen , (2) the remodeling of the glycogen substrate to permit further degradation , and (3) the converson of glucose -1 phosphate into glucose 6- phosphate for further metabolism . The glucose 6- phosphate derived from the breakdown of glycogen has three facts it is the initial substrate for glycolsis (2) it can be processed by the pentose phosphate pathway to yield NADPH and ribose derivatives , and (3) it can be converted into free glucose for release into the bloodstream . This conversion takes place mainly in the liver and to a lesser extent in the intestines and kidneys.
