Figure 37.11 Pancreatic tumors may cause excess secretion of glucagon. Type I diabetes results from the failure of the pancreas to produce insulin. Which of the following statement about these two conditions is true? A pancreatic tumor and type I diabetes will have the opposite effects on blood sugar levels. A pancreatic tumor and type I diabetes will both cause hyperglycemia. A pancreatic tumor and type I diabetes will both cause hypoglycemia. Both pancreatic tumors and type I diabetes result in the inability of cells to take up glucose.
Secretory cells of the mucous membrane of the mucosal layer of the gastrointestinal tract (GI tract) are classified as ___ cells if they secrete fluids and enzymes into the lumen and ___ cells if they release hormones into the bloodstream. Group of answer choices exocrine : endocrine endocrine : absorptive endocrine : exocrine exocrine : absorptive
Chronic stress or GC exposure can cause insulin resistance. The influence of GC on insulin is complex, but leads to hyperinsulinemia (high circulating insulin levels) and insulin resistance. Insulin resistance is typically caused by a decreased number of insulin receptors on the cell surface. Speculate on a mechanism resulting in a decreased number of insulin receptors.
Glycogen breakdown is stimulated by a signaling cascade that is an excellent example of signal amplification. Amplification in glycogen breakdown is where a small number of signal molecules (hormones) activate a rapid and large release of glucose. Which of the following is the correct sequence for this signaling cascade in skeletal muscle cells? O epinephrine, GPCR, Protein kinase A (PKA), phosphorylase b kinase O insulin, insulin receptor (RTK), protein phosphatase-1 (PP1), glycogen phosphorylase glucagon, GPCR, Protein kinase A (PKA), glycogen synthase O epinephrine, protein phosphatase-1 (PP1), phosphorylase b kinase, glycogen synthase insulin, insulin receptor (RTK), protein phosphatase-1 (PP1), bifunctional enzyme, glycogen synthase
How does a compound that inhibits the GTPase activity of G-alpha affect liver cell responses to epinephrine? It would increase proliferation. It would decrease glucose production. It would decrease proliferation. It would increase glucose production.
Many functions in the body are controlled by hormones – chemical signals that are secreted by one organ or tissue, but have effects in multiple areas. Calcium can enter the body from what we eat and drink. It circulates through blood and is used by many organs, so it’s level is carefully regulated. The amount of calcium in the blood is maintained at a relatively constant level by two hormones; for our purposes, we’ll just call them hormone A and hormone B. Hormone A is secreted by the parathyroid gland and it functions to increase blood calcium levels. Hormone B is secreted by parafollicular cells (C cells) in the thyroid gland and it functions to decrease blood calcium levels. Calvin, a teenage boy, begins eating ChocoRite™ Calcium Bites, a very tasty calcium supplement. He likes them so much that he ends up eating a whole package one afternoon. 1.Where does hormone B come from? A)From the calcium regulatory cells B)From the parathyroid gland C)From calcium supplements,…
individually, growth hormone and cortisol each cause a small amount of lipid breakdown in fat cells. When both hormones are present together they cause a very large amount of lipid breakdown. This is an example of _____. synergistic effects of hormones upregulation of hormone secretion due to negative feedback a possitive feedback loop where hormone secretion continues to increase
Hormone release and regulation is a complex interplay of control systems, feedback pathways and the concentration of circulating substances. Demonstrate your understanding of how negative feedback systems work by considering what would happen if the usual mechanisms no longer applied. You may like to think about an ectopic source of adrenocorticotropic hormone (ACTH), as secreted from a small cell carcinoma of the lung, as an example. In your explanation of how negative feedback systems can be derailed, describe how hormone/s released from the target endocrine organ usually regulate the feedback loop.
Which of the choices listed below is the correct order of events for the action of lipid-soluble hormones? O Hormone diffuses across cell membrane, hormone binds to receptors, translation of new protein, transcription of mRNA, cell's activity is altered. O Hormone binds to DNA, hormone binds to receptors, cell activity is altered, transcription, and translation. O Hormone diffuses across cell membrane, binds to receptors, receptors bind to DNA, transcription of mRNA, translation of new protein, cell's activity is altered. O Hormone binds to receptor, translation of protein, gene expression is turned on, cell's activity is altered. Save for Later Attempts: 0 of 3 used FB Submit Answer
In 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.
In their mechanism of action, a difference between steroid and nonsteroid hormones is that __________. nonsteroid hormones bind to DNA steroid hormones enter the nucleus of the target cell, and nonsteroid hormones do not nonsteroid hormones cross the plasma membrane more readily than do steroid hormones steroid hormones use a signal transduction pathway
Which of the following is a consequence of insulin signaling? (select all that apply) Cell growth/division genes upregulated Increased cellular glucose uptake through GLUT4 transporter glycogen degradation Glucose synthesis
