Glucagon serves to increase blood glucose concentrations by releasing glucose stored in liver cells into the blood. What is the function of its antagonist, insulin?

	a.	to increase blood glucose levels
	b.	to decrease blood glucose levels
	c.	to increase blood sodium levels
	d.	to increase blood calcium levels

Expert Solution

Glucagon serves to increase blood glucose concentrations by releasing glucose stored in liver cells into the blood. the function of its antagonist, insulin is to decrease blood glucose levels.

Together, insulin and glucagon help maintain a state called homeostasis. This balance helps provide sufficient energy to the cells while preventing the nerve damage that can result from consistently high levels of blood sugar. Both help manage the blood glucose levels in the body but they have opposite effects.

Insulin is a protein-based hormone that is secreted by the beta cells inside the pancreas whenever the pancreas senses that the blood sugar is too high. Low levels of insulin are constantly being secreted into the bloodstream by the pancreas, even when blood glucose levels are normal.

When the body does not convert enough glucose, blood sugar levels remain high. Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy.

When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.

When the blood glucose concentration is low, the pancreas secretes glucagon to signal the liver to produce glucose and glucose-1-phosphate. Which metabolic steps are involved in this biosignaling pathway? I. Inactivation of glycogen synthase via phosphorylation by protein kinase A II. Activation of glycogen synthase via phosphorylation by protein kinase A III. Activation of phosphofructokinase-2 via phosphorylation by protein kinase A IV. Activation of fructose-2,6-bisphosphatase via phosphorylation by protein kinase A V. Activation of phosphofructokinase-1 by fructose-2,6-bisphosphate VI. Inhibition of...

Describe the general effects of blood insulin and blood glucagon on 1) glucose uptake by cells and 2) catabolic/anabolic reactions in the body. Distinguish between catabolic and anabolic reactions.

Unlike liver cells, muscle cells do not secrete glucose into the blood. What about glucose-6-P prevents its secretion and how do liver cells overcome this problem? McArdle’s disease (also called glycogen storage disease V) is a genetic disorder in which muscle cannot make functional phosphorylase. Speculate as to why McArdle’s patients show muscle fatigue (tiredness) with even moderate exercise. McArdle’s disease is inherited as a recessive trait. Consider the activity of the phosphorylase enzyme and suggest an explanation for the...

The blood glucose concentration is controlled by the liver. It removes glucose from the blood stream and stores it when the blood glucose concentration gets too high and it releases glucose to the blood stream when its concentration gets too low. Unlike HK II, it needs to be able to respond to a range of glucose concentrations. As a result, hexokinase activity in liver has a different concentration dependence profile compared to HK II in muscle—HK IV is NOT a...

As the result of its signal transduction, the concentrations of ________ are decreased and, ultimately, _________ flux is increased by its allosteric regulatory effects. Select one: a. Fructose-2,6-bisphosphate ::::::: glycolytic b. AMP :::::::: glycolytic c. Fructose-2,6-bisphosphate ::::::: gluconeogenic d. AMP ::::::: gluconeogenic e. None of these

PART A: In a liver cell at 37 ?C the concentrations of both phosphate and glucose are normally maintained at about 5 mM each. What would be the equilibrium concentration of glucose-6-phosphate, according to the above data? ANS: Equilibrium concentration = 1.2×10?7 M PART B: This very low concentration of the desired product would be unfavorable for glycolysis. In fact, the reaction is coupled to ATP hydrolysis to give the overall reaction ATP+glucose?glucose?6?phosphate+ADP+H+ What is ?G?? for the coupled reaction?...

1. Liver metabolism during prolonged fasting. A) What happens when your glucose stored as liver glycogen is gone. What options does the liver have to provide fuel to the brain? B) During starvation muscle tissue is at first used, but then there is a shift to another fuel source. This saves muscle tissue necessary for life (such as muscles of the diaphragm needed for breathing). What is this alternative fuel source?
