BISC 3166 Study Guide - Midterm Guide: Adenylyl Cyclase, Nernst Equation, Posterior Pituitary
Document Summary
Cell communication types (i. e. paracrine, autocrine vs hormone) Ligand-gated ion channels: ligand binding opens an ion channel. Tyrosine kinase: activates protein kinases which phosphorylate and activate a protein; is a receptor enzyme. Gpcr: most common; trimeric; crosses membrane 7 times; gdp gtp activates it; can activate adenyl cyclase which will result in pka being activated. Phospholipase c system! (i. e. ligand binding to membrane receptor g protein dissociates activates phospholipase c pip2 breaks down dag + ip3 +p enzyme. Contact-dependent integrin receptors: when activated, cause structural changes in cytoskeleton. Know what creb is (increase in camp pka creb nuclear response element changes in gene expression. Hormone can affect what cell processes (i. e. apoptosis) Anterior vs posterior pituitary (which one is a true endocrine gland of epithelial origin vs extension of neural tissue of the brain that secretes neurohormones made in the hypothalamus?) Na/k atpase: 3 na+ out for ever 2 k+ in.
