explain the homeostasis of glucose in blood

Expert Solution

The pancreatic hormones insulin and glucagon are involved in homeostasis of glucose in bloodstream and they maintains the blood glucose level by opposing and balancing activity.

When blood glucose level becomes low, it triggers the release of glucagon from the alpha cells of the pancreas islet of Langerhans. Then, glucagon acts upon hepatic cells for glycogenolysis for elevating the blood glucose level. The glucagon is also involved in hepatic and renal gluconeogenesis to increase the endogenous blood glucose level in case of very low glucose condition in the body.

When exogenous blood glucose level rises, it triggers the release of insulin from the beta cells of the pancreas islet of Langerhans. Then, insulin acts upon muscle and adipose tissue and causes insulin dependent uptake of increased glucose molecules and reduces the blood glucose level. Therefore, insulin acts as anabolic hormones and performs glycogenesis, lipogenesis and maintains the blood glucose level.

Describe how vertebrates maintain blood glucose homeostasis. Why is the regulation of blood glucose levels so important for the success of vertebrates? Compared with squid and shrimp, vertebrates can tolerate longer periods of anaerobic activity. Explain the metabolic adaptations that make this possible.

Why is glucose homeostasis so important? What are symptoms of high/low blood glucose?

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...

Explain the mechanism of blood pressure homeostasis. Your answer should state the name of the reflex that maintains constant blood pressure and identify all 5 components of the negative feedback loop. Also, describe in detail how the body would compensate for a rise in blood pressure, including the division of the autonomic nervous system stimulated.

5. Blood Glucose Let x be a random variable that represents the level of glucose in the blood (milligrams per deciliter of blood) after a 12-hour fast. Assume that for people under 50 years old, x has a distribution that is approximately normal, with mean µ =85 and estimated standard deviation ợ =25 (based on information from Diagnostic Tests with Nursing Applications, edited by S. Loeb, Springhouse). A test result x < 40 is an indication of severe excess insulin,...
