WebAug 1, 2012 · Glycolysis, a simple pathway of glucose metabolism, critically regulates insulin secretion and metabolic functions of various cells. Depending on cell types, rates of glycolysis are determined at ... WebFew elaborate studies on the effects of GH on glucose metabolism in GH deficient patients have been conducted. These patients are hypersensitive to the actions of insulin on glucose metabolism and there is some evidence that when GH initially is given to such patients in the GH deprived state, paradox insulin-like effects of GH may be observed. aws backup ebsボリューム 復元 https://britishacademyrome.com
