Question

Question 48 1 pts What is a major effect of the following hormones? Glucagon stimulates fat storage Cortisol stimulates glucose storage Insulin causes Type I diabetes Angiotensin Il causes vasoconstriction Thyroid hormone stimulates iodine absorption by the GI tract

Answer 1

1)option D is the correct answer.Because the major effect of a hormone that is mentioned here only is Angiotensinogen II which causes vasoconstriction..Angiotensinogen II has it effects on blood vessels,it increases the blood pressure by causing constriction of the blood vessels,it is called as vasoconstriction.Glucogon stimulates glycogenolysis not fat storage and also it is not an effect caused by that hormone.Cortisol stimulates gluconeogenesis,ie glucose storage.The statement is correct,but it is not an effect caused by that hormone,instead it is its function.Cortisol has an effect in salt and water balance and controlling blood pressure levels.Type I diabetis is caused when insulin producing cells are damaged or destroyed and stop producing insulin.The resulting insulin defeciency leads to type I Diabetis.Effect of insulin is to control blood glucose level by signaling the liver and muscle and fat cells to take glucose from the blood.The active uptake of iodide appears to be the main control point for hormone synthesis and is stimulated by the pituitary hormone called thyrotrphin which is a thyroid stimulating hormone.

2)option A is the correct answer.Because lipid soluble hormones are located within the cytoplasm or nucleus of the cell,ie it is located within the cell.The binding of the hormone allows the receptor to influence transcription in the nucleus,either alone or in association with other transcription factors.Lipid soluble hormones include steroid hormones and eicosanoid hormones.Among these steroid are derived from cholesterol and eicosanoid hormones are synthesized from fatty acids that compose the plasma membrane.These hormones are lipid soluble ,so they can pass through the plasma membrane.eicosanoids are not stored in the cell,they are synthesized as they required,and steroids are also not stored in the vesicles itself.They are regulated by hypothalamus and pituitary because testosterone,estrrogen,progesterone all are steroid hormones which are regulated by hypothalamus and pituitary.
