A) toxic goiter and Graves disease B) myxedema and cretinism C) Graves disease and Cushing syndrome D) Cushing syndrome and Addison disease E) Graves disease and Addison disease 4. Which of the following hormones is secreted by the adrenal medulla? A) glucagon B) insulin C) aldosterone D) cortisol E) epinephrine 5. Which of the following hormones regulates calcium levels in the blood? A) thyroxine B) triiodothyronine C) calcitonin D) cortisol E) aldosterone 6.
What are the pharmacodynamics: a. ‘Blockade of beta-adrenergic receptors produces significant action on the cardiovascular, renal and respiratory systems and on the eye. This blockade also results in metabolic and endocrine effects’ (Woo & Wynne, 2012, p. 184). b. Clinical pharmacology studies have confirmed the beta-adrenergic blocking activity as shown by: (Micromedex, 2015).
Extra glucose cannot be used because of insulin deficiency and and blood glucose level rises, which contributes to further, adding to the osmotic diuresis. 4. What acid-based disturbances commonly occur and why? Arterial blood pH less than 7.30, serum bicarbonate level less than 15 mEq/L (15 mmol/L), and moderate-large ketones in the urine or blood ketones. 5.
Lumbricalis variegates cardio vascular system has a myogenic nature(myogenic-depolarisation impulses for heartbeats originating in muscle cells), the dorsal and ventral blood vessels have peristaltic pumps (Halfmann & Crisp 2011). The chemicals chosen as the treatment is ethanol and nicotine, it is assumed that ethanol will slow the pulse rate in the cardio vascular system and that nicotine will speed it up, because of these stimulant and depressant nature. Materials & Method: * Blackworms Lumbricalis variegates (35) * Petri dishes (8) * Pipettes (8) * Paper towel * Recovery bowl * Microscope * Stopwatch * Slides
Exploring enzymes through Lactex. Problem: Does pH affect the results of Lactex? Independent Variable: pH value Dependent Variable: Glucose Control: Lactex enzyme Hypothesis: I think pH will cause the result of Lactex to change. Materials: · Soap (basic) · Antacid (basic) · Soda (acidic) · Vinegar (acidic) · pH test strips · eye dropper · Cow’s milk Experimental Design: 1. Set up plastic cups 2.
Lactase Buffer solutions 4,7,9 Enzymes are organic catalysts that control the rate of chemical reactions in cells while not being permanently altered themselves. In general, enzymes speed up the rate of reaction by lowering the activation energy required to start reactions. Lactase is an enzyme used by the body to hydrolyze lactose, a disaccharide unique to mammalian milk, into the monosaccharaides, glucose and galactose. Lactose has been shown to aid in the absorption of several minerals, including calcium, magnesium, and zinc. .
adrenal medulla/adrenaline * Paracrine - that secretes hormones that affect adjacent cells e.g. gastric mucosa/gastrin/gastric pits. * Autocrine – regulate their own avtivity by the secretion of hoirmone e.g. interstitial cells of testis/testosterone Each target cell in the body is regulated only by those hormones to which it has receptor molecules , and not y others.different cells may respond in different ways to the same hormone – the transduction machinery of different target cells ‘reads’ the hormone signal in different ways. Blood hormone concentrationare usually governed by negative feedback control – a reduction in concentration stimulates additional secretion and an increase in concentration inhibits further secretion.
Epinephrine . Melatonin . Glucagon 25. Which hormone secreted by the pituitary gland functions to make the tubules more permeable to water, thereby increasing water’s absorption? A. Atrial Natriuretic Hormone B. Anti Diuretic Hormene C. Follicle Stimulating Hormone D. Insulin Like Growth Factor 26.
Carb-Cutter; Blocker of Carbs or a Phony? Rumor has it that there is a miracle weight loss product that slows down the digestion of carbohydrates. These diet pills contain carb-cutter which blocks amylase, the enzyme that breaks down starch into glucose. With this being done, Carb-Cutter neutralizes the amylase before it starts the breakdown. This allows your body to pass starch through without turning it into glucose.
Secretes pancreatic juice, insulin, glucagon, duodenum, and somatostatin into the bloodstream. Regulates blood sugar and completes the breakdown of protein, carbohydrates and fats 17. Responsible for the production and maintenance of the protective mucous blanket by synthesizing and secreting glycoproteins known as mucins. 18. Stores and concentrates bile 19.
