Which is true regarding insulin secretion from the pancreas?Insulin secretion favors glycogenolysis.The presence of glucokinase is one factor that allows the pancreas to appropriately release insulin.Insulin is produced and released from the alpha cells in the islet of Langerhans.In a type I diabetic, the pancreas must secrete more insulin to deal with the increase in insulin resistance in peripheraltissues.

Which of the following are true about how pancreatic β cells sense blood glucose levels and release insulin? (select all that apply) Group of answer choices The first step of glycolysis (producing glucose 6-phosphate) is more efficient in pancreatic β cells than in muscle glucose transporters in pancreatic β cells have a higher affinity for glucose than the transporters in other tissues Increased production of ATP is used as a signal that blood glucose is high Insulin is released when blood glucose levels are high Increases in ATP open a K+ channel Influx of Ca2+ stimulates insulin release

Which of the following statements is true regarding the blood glucose level of non-insulin-dependent diabetics compared with that of normal individuals? O Blood glucose levels of diabetics tend to be very stable, but at a higher level. O Blood glucose levels of diabetics tend to be variable and higher. O Blood glucose levels decrease more rapidly following a meal, often dropping lower than is toleráble. O Blood glucose levels average the same level in diabetics but reach higher peaks for short periods. O None of the above is true.

It is determined that he has parathyroid deficiency due to inadvertent damage to the parathyroid glands because his signs and symptoms include Group of answer choices a low plasma Ca2+ level, increased muscular excitability, and spasm of the muscles of the upper extremity (Trousseau sign) low plasma phosphate and Ca2+ levels and tetany low plasma phosphate and Ca2+ levels and tetanus increased muscular excitability, a high plasma Ca2+ level, and bone demineralization.
For both T1DM and T2DM, describe the following: Causes Symptoms Treatments Glucose levels Insulin levels Insulin receptor sensitivity Also please discuss the cause/effect relationship between acute and chronic stress (chronic disease or homelessness, for instance) and T1DM and T2DM. What is the mechanism by which the nervous system impacts stress hormones? Are there neurotransmitters involved? Which neurotransmitters? Which stress hormones?
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.
Considering the endocrine function of adipose tissue, why is it so hard for people to maintain weight loss? I was thinking from the adipose tissue there is: adiponectin → hormone synthesized by adipose cells → reduce cellular insulin resistance + protects blood vessels from inflammation + atherosclerosis. However, the levels of the hormone are lower in people who are obese. But I'm not sure if that is correct or not.

How might dysregulation in the PPP contribute to complications such as slow wound healing and peripheral neuropathy in diabetic patients? Impaired nucleotide synthesis. Elevated insulin sensitivity. Lactic acid accumulation. Reduced oxidative stress.
