Which of the following is/are true about the body's glycogen stores?

a. Liver glycogen stores are larger than glycogen stores elsewhere in the body b. skeletal muscle glycogen stores are larger than glycogen stores elsewhere in the body c. Skeletal muscle glycogen stores can be broken down to maintain blood glucose d. Liver glycogen stores can be broken down to maintain blood glucose e. The body's largest glycogen stores are found in skeletal muscle and the pancreas f. Beyond moderate intensities, most carbohydrate catabolism comes from glycogenolysis, not circulating glucose b, f

The endocrine response to stress would does NOT include which of the following responses?

a. an increase in salt and water retention due to increased vasopressin and aldosterone secretion b. increased breakdown of stored fuels like glycogen and triglycerides due to increases in insulin c. all of these ARE part of the endocrine response to stress d. an increase in circulating fuels like glucose and fatty acids due to the actions of glucagon, epinphrine and cortisol e. an increase in blood pressure due to increases in epinephrine, angiotensin II, aldosterone, and vasopressin b

Which of the following is/are NOT part of how we make thyroid hormones?

a. binding of a monoiodiotyrosine with diiodotyrosine forms T3; this takes place in the thyroid follicular cells b. binding of a diiodotyrosine with diiodotyrosine forms T4; this takes place in the colloid c. The attachement of one iodine to thyroglobulin (which contains tyrosine) forms mono-iodotyrosine; this takes place in the colloid d. three of these e. the binding of iodine to thyroglobulin is catalyzed by thyroperoxidase a

Which of the following hormones would increase glycogenesis? select all that apply

a. epinephrine

which of the following is/are enzymes that would tend to increase glycogenesis?

a. glycogen synthase

The endocrine response to stress would NOT cause which of the following responses?

which of the following best describes circulating insulin levels in type 2 diabetes mellitus?

a. insulin levels are low because of greater renal clearance b. inslulin levels are low because the factors that normally cause its secretion are not present c. circulating insulin levels are often elevated because glucagon stimulates insulin secretion d. insulin levels are low in newly diagnosed type II diabetic patients because the pancreas is not producing it e. circulating insulin levels are often elevated because blood glucose remains high even when it is secreted e

Circulating calcium concentrations are normally tightly regulated by the endocrine system. Which of the following are NOT important roles of calcium in the body?

a. it plays an important role in neurotransmitter secretion at synapses b. it plays an important role in formation of blood clots c. all of these ARE important roles of calcium in the body d. it plays an important role in normal electrical events in cardiac pacemaker cells and cardiac muscle cells e. it plays a critical role in regulating muscle contraction f. it is important for normal bone mineralization and strength c

Which of the following is/are true about endocrine control of calcium homeostasis?

a. parathyroid hormone is essential for life b. calcitonin secretion goes up when plasma calcium concentrations are low c. parathyroid hormone secretion goes up when plasma calcium concentrations are low d. when circulating calcium concentrations are low we increase bone resorption e. three of these b
