Select the fundamental properties of all ion channels.
ligand‑gated
rapid transport
use active transport
selectivity
Fundamental ion channel characteristics include selectivity and gating. Channels differ in the number and types of ions they will pass (selectivity). Channels can be mechanically, ligand and/or voltage gated.
Correct option is : • ligand- gated
• selectivity
Select the fundamental properties of all ion channels. ligand‑gated rapid transport use active transport selectivity
determine whether each term or phrase describes ligand-gated ion channels, voltage-gated ion channels, or both.
Although the ligand-gated ion are ion channels they are considered to be receptors as they only open when bound by which of the following? select two answers please- 1)protein 2)ligands 3)drugs 4)ions 5)sugars
QUESTION 18 Gated ion channels include each of the following except O A. voltage-gated channels. OB. mechanosensitive channels. O C. ligand-gated channels. OD. potassium leak channels. E. All of these are types of gated channels
Receptors that bind IP3 are generally metabotropic receptors GPCRs receptor tyrosine kinases ligand-gated ion channels
1) Which ligand-gated ion channels does (glutamate / GABA / glycine) open? 2) How do changes in (potassium / sodium) concentration affect the resting membrane potential? 3) If (sodium / potassium / chloride) channels are locked open, the membrane potential will continue to change due to ion flow until it reaches what value? (give a numerical value)

You are studying a ligand-gated ion channel. The ligand is a neurotransmitter. Upon binding the neurotransmitter, the ion channel opens and Na+ flows into the cell. The receptor is found on the dendrites of frog neurons. You are going to use one of the patch-clamp variations to study the effect of (1) the neurotransmitter and (2) second (and separately) the effect of an antagonist. Explain the patch-clamp technique variation you would use and why. Explain how you will study the...
29 From the following graph, which channels/pumps are open/active at position 4? Mark all that apply A. Na+/K+ Pump B. Voltage gated Na+ Channel C. Voltage gated K+ Channel D. Passive K+ channel E. None of the pump/channels are open/active Membrane potential (m)
Ion channels are involved with generating action potentials. Below is an electrical profile of a neuronal action potential. In the boxes below list whether the channels are all open, all closed, opening, or closing at each of the letters shown in the profile. (Opening implies that channels were "all closed" and are moving toward their "all open" state. Closing indicates the opposite. Use the term "closing" to represent the inactivated state of the Na+ channels.) (7 pts) 1. Channel Type...
Which of the following statements are accurate? Select all that apply Interneurons are responsible for analysis of stimuli and forming a circuit to respond to the stimuli. Interneurons can interact (e.g. stimulate) with muscle cells or glands. The peripheral nervous system is able to carry information to and from the central nervous system. Nerves typically collect sensory information such as light, touch, or blood pressure. Interneurons are a type of sensory neuron. Which of the following statements are accurate? select...
