PSL300H1 Study Guide - Final Guide: Circadian Rhythm, Anterior Pituitary, Pancreatic Islets
Document Summary
When plasma attach to membrane receptor with tyrosine kinase activity. Cells go into catabolic metabolism glucose levels go down, insulin stops being released. Some bound to sulfate and bind to g-protein- Neurons, pancreatic endocrine cells, heart, blood vessels, autonomic nervous system; coupled receptors adipose tissue. Circadian rhythm of tonic secretion; stress enhances release. Dissolved in plasma, attach to g-protein- coupled receptor. Targets most tissues, causes corticosteroid-binding globulin gluconeogenesis & glycogenolysis; protein catabolism. Targets most cells of body and nuclear receptor. Negative feedback on albumins metabolic enzyme activity and. Circadian rhythm of tonic secretion; influenced by circulating nutrients, stress, and other hormones. Dissolved in plasma, bound to binding protein with structure identical to that of gh receptor. Trophic on liver for insulin-like growth factor production; also acts directly on many cells. Bound to plasma protein drop in ca2+ levels, indirectly via pth. Dissolved in plasma thyroid gland (parafollicular cells) levels also initiates protein synthesis increase in plasma in osteoclasts.
