Answer:
1) B) insulin
2) A) glucagon
3) C) epinephrine
4) B) insulin
5) A) glucagon
6) A) glucagon
Explanation:
High levels of glucose in the blood promote the release of insulin hormone which functions to stimulate uptake and utilization of glucose by cells. Insulin may also act to inhibit lipolysis in adipocytes and stimulates triglyceride storage. Glucagon hormone controls blood sugar (glucose) by stimulating glycogenolysis (conversion of glycogen to glucose), promoting gluconeogenesis (glucose synthesis), and inhibiting glycolysis (glucose breakdown). Moreover, glucagon also can increase ketogenesis (i.e., the production of ketone bodies by breakdown of fatty acids and ketogenic amino acids) when insulin is inhibited. Finally, epinephrine hormone binds to receptors localized on the surface of muscle cells, which stimulate the production of cyclic-AMP (cAMP), a second messenger (i.e., a signaling molecule).
What part did you need help understanding? Your definition is pretty strong- the epiglottis keeps food from entering the trachea and lungs. It also opens during breathing to allow air into the lungs. Good luck on your test, let me know if you need anymore refreshers!
