Liver glycogen is used in fasting to provide
glucose for use by other tissues including the brain.
Muscle glycogen is not. What is the explanation for
this?
Liver glycogen is used in fasting to provide glucose for use by other tissues including the brain. Muscle glycogen is not. What is the explanation for this?
- A) Muscle does not have a debranching enzyme.
- B) Muscle cannot degrade glycogen further than glucose-1-phosphate
- C) Muscle lacks glucose-6-phosphatase. (correct)
- D) The liver provides all the glucose necessary for metabolism and there is no need for muscle to do the same.
Which of the following is NOT a function of glucagon?
Which of the following is NOT a function of glucagon?
- Raising blood glucose levels
- Stimulating glycogen production from glucose
- C) Stimulating the release of glucose from the liver
- ) Increasing glucose production from fatty acid (correct)
) Which of pathway for glycogen breakdown in the
liver would prevent the cell from breaking down
glycogen in response to EPINEPHRINE
) Which of pathway for glycogen breakdown in the liver would prevent the cell from breaking down glycogen in response to EPINEPHRINE
- One that prevents it from hydrolyzing GTP
- . One that destroys its GTPase activity
- . One that prevents it from binding GTP
- One that causes it to constitutively (constantly) activate Phospholipase C (correct)
When glucose enters the beta cell, it is used to
produce ATP. The increase in ATP causes an influx of
a substance which causes the exocytosis of insulin.
What is this substance?
