【多选题】What are the metabolic changes in diabetes?
A.
Due to defect in insulin production or action, individuals with either type of diabetes are unable to take up glucose efficiently from the blood; recall that insulin triggers the movement of GLUT4 glucose transporters to the plasma membrane in muscle and adipose tissue. Uncontrolled diabetes is characterized by high glucose levels in the blood and urine and the production and excretion of ketone bodies.
B.
With glucose unavailable to cells, fatty acids become the principal fuel, which leads to another characteristic metabolic change in diabetes: excessive but incomplete oxidation of fatty acids in the liver.
C.
The acetyl-CoA produced by β oxidation cannot be completely oxidized by the citric acid cycle, because the high [NADH]/[NAD + ] ratio produced by β oxidation inhibits the cycle.
D.
Accumulation of acetyl-CoA leads to overproduction of the ketone bodies, acetoacetate and β-hydroxybutyrate, which cannot be used by extrahepatic tissues as fast as they are made in the liver. In addition to β-hydroxybutyrate and acetoacetate, the blood of individuals with diabetes contains small amounts of acetone, which results from the spontaneous decarboxylation of acetoacetate.
