Define Ligand/Chemically-gated ion channels. What stimulates a ligand-gated channel to open versus a voltage-gated channel to open? What is a voltage-gated ion channel? Describe how ligand-gated channels are related to graded potentials.
What does the ligand do in the ligand gated channel? ligand (messenger) binds to the receptor and then opens the "gate" to let ions in What is a voltage gated ion channel? responsible for generation info in the form of P with the CNS,PNS, & cardiovascular system ...
What are three ways ion channels can be gated? There are three main types of gated channels: chemically-gated or ligand-gated channels, voltage-gated channels,and mechanically-gated channels. Ligand-gated ion channels are channels whose permeability is greatly increased when some type of chemical ...
What stimuli can open or close the gate ion channel? What stimulates a ligand-gated channel to open versus a voltage-gated channel to open? Name the three types of gated channels. Mechanically gate ion channels open in response to what? Define Ligand/Chemically-gated ion channels...
The serotonin receptor type 3 is a pentameric ligand-gated ion channel regulating intestinal motility, nausea, and vomiting in humans. The HTR3B gene codes... MV Tzvetkov,C Meineke,E Oetjen,... - 《Gene》 被引量: 116发表: 2007年 The multiple murine 3 beta-hydroxysteroid dehydrogenase isof...
The nicotinic acetylcholine receptor is a prototype ligand-gated ion channel that mediates signal transduction in the neuromuscular junctions and other cholinergic synapses. The molecular basis for the energetics of ligand binding and unbinding is critical to our understanding of the pharmacology of this...
The ion channel forming colicins beautifully exemplify both properties. Recent results delineate the structure of a whole colicin; coupled with new biophysical studies, a mechanism for insertion is proposed.doi:10.1016/B978-0-444-81125-7.50018-9ROBERT M. STROUD...

lipotoxin isolated from the latex of Euphorbia gum plants can also activate VR1 and has a more powerful effect. Capsaicin is a competitive antagonist of VR1, but it does not cause pain or analgesia by itself. This means that it does not have a corresponding ligand that binds to the pain...
Which membrane protein is responsible for restoring the resting membrane potential and proper concentration of ions inside and outside a cell? a. The ATP Na^+/K^+ pump. b. The ATP O_2/CO_2 pump. c. Ligand-gated Na^+ channels. d. Voltage-gat...
