True False Cytokines are peptides that are generally made in advance by specific types of cells, stored in vesicles, and act as autocrine or paracrine factors. True False Thyroid hormone is stored in an extracellular compartment. True Falsearrow_forwardChemical signals Both autocrine and paracrine signaling molecules are carried by the blood to a distant target. Hormones (such as insulin & glucagon) are released directly into extracellular fluid and then enter the circulatory system, which carries them to a distant target. Neurohormones are paracrine signaling molecules that travel exclusively in interstitial fluid to reach their target.arrow_forward
