Document Summary
Events at the post-synaptic membrane: neurotransmitters bind to ligand gated channels, ion channels open to move membrane towards or away from threshold, small local depolarization of the membrane, neurotransmitters taken up by pre-synaptic membrane or degraded by enzymes. What are neurotransmitters and what do they do. Chemical messengers that signal a cell to perform certain ways. What are the receptors on the post- synaptic membrane. Channels that a molecule binds to the receptor or near the channel to change the conformation or shape and open it. How is an action potential propagated down a nerve cell axon. Transcription: copy of dna strand is made into mrna. Mrna leaves nucleus through nuclear pores and attaches to ribosomes trna brings appropriate amino acids as it reads mrna codons. A molecule binds to the receptor or near the channel to change the conformation/shape and open it.
