Gated channels Study guides, Class notes & Summaries

transport proteins - are responsible for controlling passage across the membrane fluid mosaic model - The membrane is a mosaic of protein molecules bobbing in a fluid bilayer of phospholipids fatty acid tails - nonpolar, hydrophobic fatty acid heads - hydrophilic, polar periphial proteins - bound to the surface of the membrane integral proteins - penetrate the hydrophobic core (ones that span the membrane are transmembrane protiens How do cells recognize each other? - by binding to molec...

In order to provide feedback on the weekly quizzes, I will provide rationale statements for the quiz questions. You will note that there are more than 5 listed this is because the quiz testbank is larger than 5 questions and the additional information can help you prepare for the final and direct your study.  The amygdala is associated with anxiety and perception of odors.  The hippocampus is involved in memory and anxiety. The amygdala is associated with anxiety and perception of o...

Porth’s Essentials Of Pathophysiology 5th Edition Test Bank 1. Chapter 1 Although the basic structure of the cell plasma membrane is formed by a lipid bilayer, most of the specific membrane functions are carried out by: A) Bound and transmembrane proteins B) Complex, long carbohydrate chains C) Surface antigens and hormone receptors D) A gating system of selective ion channels Ans: A Feedback: The functions of plasma membrane depend on the presence of proteins that are bound in the lipid bilay...

Benzodiazepines (Diazepam, Lorazepam, Clonazepam, Clobazam) correct answer: Increase GABA-ergic neurotransmission. Diazapam: Status epilepticus Lorazepam: Status epilepticus Clonazepam: absence seizures (blocks t-type Ca2+ channels) Clobazam: Lennox-Gastaut syndrome WITHDRAWAL TRIGGERS SEIZURES. SEDATION & RESPIRATORY DEPRESSION Other adverse effects: CNS depression, GI upset, suicidal behavior Carbamazepine correct answer: Blocks voltage-gated Na+ channels by binding to inactivation...
