Serum proteins bind to the “steroid” form of these molecules to increase their water solubility, allowing them to be transported through the blood. For 10 points each:
[10e] Name these signaling molecules that regulate various aspects of physiology and behaviour, which include estradiol and testosterone.
ANSWER: hormones [accept steroid hormones; accept sex hormones]
[10m] Hormones are secreted from endocrine glands via this form of active transport. This process involves the docking and fusion of vesicles at porosomes, where they release their contents into the extracellular space.
ANSWER: exocytosis [reject “endocytosis”]
[10h] These other signaling molecules, which include interleukins and tumor necrosis factors, play an important role in the immune response. A “storm” of these molecules following infection can cause multisystem organ failure.
ANSWER: cytokines [accept cytokine storms or cytokine storm syndrome]
