BIOL 1201 Study Guide - Final Guide: Cell Junction, Blood Vessel, Paracrine Signalling
Document Summary
Distant (hormonal) into target: endocrine cells secrete hormones into blood vessel and releases. Describe the basic steps involved in cell signaling. Reception: contact of the signal molecule (ligand) and the receptor (protein, local signaling: target cells because of proximity, distant signaling: has to pay attention to bind with the correct receptor (specificity) Response receptors to target molecules inside the cell: a cascade of molecular interactions that relay signals from, transforming one message in one form to another, the reaction of the cell based on reception and transduction of. Differentiate between protein and steroid hormones, in terms of where the receptors are located and the type of signal transduction pathways involved. Differentiate between signaling locally and at a distance. Local (paracrine and synaptic: cell junctions (gap, tight, (tight junctions only found in plants, cell recognition (receptor-ligand, paracrine: cell has many ligands & secretes signal molecules to, synaptic: neurotransmitter diffuses across synapse (specifically local cells.
