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

举一反三
- The sources of blood glucose include 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
- When glucose levels fall, the liver: A: releases glucagon B: stores glucose as glycogen C: breaks down stored glycogen D: makes glucose from fat
- In mammals, gluconeogenesis in the liver, kidney, and small intestine provides glucose for use by the ______, _______, and erythrocytes.
- 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:</p></p>
