Which of the following statements about the fed and fasting
metabolic states is correct?
a. In the fasting state, glucagon acts to increase the activity of
lipoprotein lipase in adipose tissue.
b. In the fasting state, glucagon acts to increase the synthesis of
glycogen from glucose.
c. In the fed state, insulin acts to increase the breakdown of
glycogen to maintain blood glucose.
d. Ketone bodies are synthesized in the liver in the fasting state,
and the amount synthesized increases as fasting extends into
starvation.
Ans : d) ketone bodies are synthesized in the liver in the fasting state, and the amount synthesized increases as fasting extends into starvation
In the fasting state when the body needs energy from the glucose. This glucose is formed by the ketone bodies by liver known as gluconeogenesis during the period of fasting .

Liver glycogen synthesis increases Muscle glycogenolysis (glycogen breakdown) increases Liver gluconeogenesis decreases Insulin levels in the blood decrease Ketone body production in the liver is increased ..... Which of the following metabolic changes will occur in a typical human during 12 hours of fasting? (Select ALL that apply.) Liver glycogen synthesis decreases Liver...
Which of the following statements about hormonal regulation of glycogen synthesis and degradation are correct? Multiple answers! A. Insulin increases the capacity of the liver to synthesize glycogen. B. Insulin is secreted in response to low levels of blood glucose. C. Glucagon and epinephrine have opposing effects on glycogen metabolism. D. Glucagon stimulates the breakdown of glycogen particularly in the liver. E. The effects of all three of the regulating hormones are mediated by cAMP.
D Question 30 Soveral hours after a meal, the brain uses During starvation, the brain uses as fuel. glucose from glycogen stored in the brain ketone bodies produced in the heart glucose from olycogen stored in the liver kolone bodies produced in the liver glucose from glycogen stored in the muscles kotone bodo produced in the liver fatty acids from adipose tissue glucose from gluconeogenesis in the liver D Question 31 Question 2 pts Which of the following enzyme pairs...
1. What is happening in a healthy individual about an hour into a glucose tolerance test? (Note: At this early time-point, blood glucose levels are still high. Also, remember that a person who is taking a glucose tolerance test was fasting for 12 hours prior to the test!) (Select ALL that apply!) Hint: Review pages 319-325, 462-467 and 489-491 of Tymoczko 3E before attempting this question. A. Glucose is being exported by the liver B. Glucose is being taken up...
An increase in intracellular phosphoinositol 3,4,5 triphosphosphate (PIP3): leads to the activation of PI-3 kinase. leads to glucose absorption via GLUT 4 in the muscle and adipose. is accomplished by the GTP-bound Gs alpha-subunit. leads to glycogen breakdown in the liver. is an intermediate in glucagon signaling that primarily occurs in the liver and adipose tissues. The following metabolic effects are accomplished by glucagon signaling: mobilization and fusion with the membrane of GLUT 4 carrying vesicles within adipose and muscle...
Blood glucose homeostasis Complete the following statements to describe how the pancreatic hormones help maintain blood glucose homeostasis. Not all choices will be used. Eating insulin _ blood glucose. When blood glucose is the pancreas secretes into the blood. glycogen breakdown This hormone is secreted by the B cells in the pancreatic islet. It stimulates the of glucose, which is stored as in the liver and muscle cells and used to form fat in the adipose tissue. increases glucose After...

Fatty acids from adipose stores are the major source of energy for red blood cells D. Muscle glycogen stores are used to maintain glucose E. Nitrogen balance is maintained because muscle...
1. Which of the folowing statements about glucokinase and hexokinase (that catalyze the same reaction) is TRUE? A. Glucokinase has a higher capacity than hexokinase to convert glucose to glucose 6 phosphate B. Hexokinase is only active in the liver where it can utilize multiple hexoses C. While glucokinase requires ATP for its action, hexokinase requires GTP D. Glucokinase can act on multiple glucose-like sugars (such as galactose) E. Hexokinase has a higher Km and easily handles all the glucose...
