Blood glucose regulation
Biology · Secondary 4 · Hard · Blood glucose regulation
After a carbohydrate‑rich meal, blood from the small intestine enters blood vessel Q and then flows to the liver in blood vessel R. Which statement correctly describes the change in blood glucose concentration between Q and R?
- It is higher in R because the liver releases glucose into the blood.
- It is the same in Q and R because the liver does not affect glucose levels.
- It is lower in R because the liver stores some glucose as glycogen.
- It is zero in R because all glucose is removed by the liver.
