Types of signaling complexes G protein (coupled receptors) Receptors which function as tyrosine kinase Intracellular receptors (for steroid hormones) Ligand-gated ion channels WORKSHEETS!!!!! Signaling in Animals Long distance signaling (hormones) Endocrine system: regulatory system, maintains homeostasis through hormones Homeostasis: steady state physiological condition Constant pH levels, body temperature, ion concentrations Hormones: regulatory chemicals, produced in endocrine glands, secreted into the blood and carried to target cells [extracellular “first” messenger] Target cells respond to hormone by altering their metabolism, they have receptor for specific first messengers -Different cell types will have a different profile of receptors Consists of hormone and the glands (endocrine glands=ductless glands) which secrete them Endocrine glands secrete hormones into the circulation Regulation results from function of the endocrine system and the nervous system
