A: supply directly by breakdown of muscle glycogen
B: supply directly by breakdown of liver glycogen
C: produced by gluconeogenic pathway
D: digestion and absorption of food
举一反三
- The blood glucose directly come from A: liver glycogen decomposition B: muscle glycogen decomposition C: digestion and absorption of dietary carbohydrates D: gluconeogenesis in liver E: glucose reabsorption in kidney
- The human erythrocyte loses its nucleus and mitochondria during differentiation. It therefore relies on _________ alone for its supply of ATP. The lactate produced by glycolysis returns to the liver, where gluconeogenesis converts it to glucose, to be stored as glycogen or recirculated to peripheral tissues. The erythrocyte has constant access to glucose in the bloodstream.
- When glucose levels fall, the liver: A: releases glucagon B: stores glucose as glycogen C: breaks down stored glycogen D: makes glucose from fat
- The metabolic changes in the body during starvation are A: hepatic gluconeogenesis increases B: free fatty acids in blood reduce C: the levels of ketone bodies in blood increase D: hepatic glycogen breakdown enhances
- after digestion and absorption of food fats， the resembled lipids in intestinal mucosal cells need （ ） to transport to blood， then to liver。 A: HDL B: chylomicron C: LDL D: VLDL

When fatty acids are readily available as fuels, their breakdown in liver mitochondria yields acetyl-CoA, a signal that further oxidation of glucose for fuel is not necessary.
