BIO 202: ENDOCRINE SYSTEM (EXAM 1)
QUESTIONS WITH CORRECT ANSWERS 2025
Endocrine system - CORRECT ANSWER -
Involves in regulation, homeostasis. Composed of ductless glands that secrete hormones
Hormones - CORRECT ANSWER -Chemical signal, binds to receptors in target tissue
Functions of hormone -LCORRECT ANSWER -Sleep, metabolism, ion homeostasis, growth, reproduction
True endocrine glands -LCORRECT ANSWER -Pituitary, thyroid, parathyroid, adrenal
Organs with endocrine function -LCORRECT ANSWER -
Heart, thymus, pancreas, gonads, kidneys, hypothalamus, stomach, adipose
TypesLof hormones based on circulation - CORRECT ANSWERL-Circulating, paracrine, autocrine hormones
Circulating hormones -LCORRECT ANSWER -
Diffuse into blood, travel throughout body, regulate target cells
Paracrine hormones - CORRECT ANSWER -Circulate in fluids, bind to receptors on local target cells
Autocrine - CORRECT ANSWER -BindsLto receptorsLon the cell that secreted it
Chemical properties of hormones -LCORRECT ANSWER -Polar & nonpolar molecules
Polar molecules(insulin, epinephrine, serotonin) - CORRECT ANSWER -
Water soluble, easily transport, receptor is on membrane of targetLcells, hormone binds to receptor(2nd
messenger)
2nd messenger(cAMP) - CORRECT ANSWERL-
Internal signal, changes enzyme function/metabolism, open/closeLion channels
