Chapter 7.3, Problem 9CC
Summary Introduction
To sketch: The diagram of a reflex pathway shows the release of glucagon in response to decreased levels of blood glucose levels.
Introduction: The glucagon is released by the alpha cells of the pancreas when the concentration of glucose (or insulin) becomes too low. The glucagon converts the stored form of glucose (glycogen) to be available to the cells in the form of active glucose. The increase in the concentration of glucose also increases the level of insulin in the body.

For our patient John with diabetes type II, he can make insulin but his body cells can be resistant to this insulin. Note: activated insulin receptors will activate glucose receptors.
John takes a drug called metformin, in conjunction with regulating his diet and exercising. This drug has two main effects. First, it helps reduce hepatic (liver) production of glucose. Second, it helps cells become more sensitive to insulin. Explain how these two effects of metformin can help John.
Blood glucose levels remain stable between meals despite the fact that the body's cells continually use glucose as an energy source. Answer the following questions on how the body maintains blood glucose at normal levels (90-100 mg/dL blood) between meals. Which cells respond to fasting? Which hormone do they produce?
asap please.
Diabetes insipidus has been identified in two males. One person did not have the condition until he had a stroke. The other had lived with the condition his whole life, and despite the existence of normal ADH receptors, it had never reacted to exogenous ADH. What might be the cause of the two men's diabetes insipidus? Provide your references.

- Congenital adrenal hyperplasia is a lifethreatening condition that results from a deficiency in the P450 enzyme steroid 21- hydroxylase. This enzyme catalyzes the first step in the conversion of progesterone into cortisol and aldosterone (Figures 26.28 and 26.29). A characteristic of congenital adrenal hyperplasia is an increase in sex hormone production. Explain why this is the case.arrow_forwardFor each of the following statements, select whether it corresponds to ADH, oxytocin, or both.

- Two men are diagnosed with diabetes insipidus. One didn’t have the disorder until he suffered a stroke. The other had a withstood the condition all his life, and it had never responded to exogenous ADH despite the presence of normal ADH receptors. What might be the cause of the diabetes insipidus in the two men?arrow_forwardThe posterior pituitary gland stores and releases the hormones oxytocin and ADH. The secretion of each hormone is regulated differently.Explain the difference between positive and negative feedback using the feedback pathways for oxytocin and ADH as examples.arrow_forwardDuring the stress response, glucocorticoids and catecholamines work synergistically (together) to exert what effect?

Use key terms: hormone, GPCR, G-protein, cyclic AMP in your response. Please include relevant diagrams and explain them.arrow_forwardIn the answer, discuss insulin and glucagon. (You do not need to talk about the other hormones that influence glucose levels when stress levels are high.) For each hormone, state the stimuli that causes secretion, the cell that secretes the hormone, the metabolic pathways stimulated by the hormone and the overall effect of each hormone.arrow_forward
