XIV) Signaling.

A) The adopt for Signaling in multicellular organisms B) yeast need to indicate to respond to various factors

C) Extracellular signboard molecules amaze to receptors 1) most bind to receptors on the cell surface 2) some(prenominal) pass through membranes 3) There argon different types of extracellular signaling molecules 4) most signaling molecules are secreted by exocytosis 5) others mild through the membrane 6) others remain bound to the surface

D) Receptors 1) usually they are on the cell surface 2) sometimes they are interior the cell

E) four major types of signaling 1) paracrine signaling 2) synaptic signaling 3) endocrine signaling 4) autocrine

F) Cells connected by gap junctions rump share petite signaling molecules 1) allow the exchange of small signaling molecules 2) no exchange of macromolecules 3) important roles in development

G) disparate types of signals can trigger different effects in a given cell 1) differentiation 2) proliferation 3) survival 4) specific cellular functions

H) different cells may respond differently to the same signal 1) answer depends on cell surface receptor 2) response depends on the environment 3) intracellular machinery 4) ex - acetylcholine (a neurotransmitter)

I) Signaling by Nitric Oxide 1) NO synthase produces NO by deamination of arginine 2) piece of NO in causing smooth muscles to relax a) rank of events b) medical relevance 3) other functions of NO

XIV. 2

a) production by delirious macrophages and neutrophils b) NO is released by many nerve cells 4) mechanisms of action of NO a) diffuses out of the cell, through the membrane b) diffuses directly into neighboring cells c) acts yet locally d) binds to enzymes within the target cells e) production of cGMP

J) Signaling via intracellular receptors 1) small hydrophobic molecules bind intragroup receptors 2) types of ligands that bind internal receptors a) cortisol b) steroid sex ductless glands c) vitamin D d) thyroid hormone e)...If you want to get a full essay, order it on our website: Ordercustompaper.com
