Does protein contain nitrogen?
yesEvery protein should contain Nitrogen.To be a protein it should contain -NH2 gruop
Which protein is usually given the 'superior' names?
Plant Protein
A chemical reaction in a living cell occurs in the presence of a specific protein molecule The concentration of this protein molecule remains the same before and after the reaction This protein mole?
its an enzyme enzymes are a type of protein
If you replace all the oxygen atoms in a protein with sulfur atoms what will happen to the protein?
Potatoes.
What happens to the neuron if sodium channels do not open?
causes chemically gated sodium channels to open
What type of transport protein is a sodium potassium pump?
It is a carrier protein
What is ligand gated ion channel?
Ionotropic receptors are ligand-gated or transmitter gated ion channels. The binding of a neurotransmitter or other ligand to a particular site on a domain of a protein in the receptor causes a conformational change in the protein subunits. This allows a certain ion to pass through, poteitally potassium, sodium or chloride. There are two types of ionotropic receptors, non-NMDA and NMDA. Both are ligand gated receptors, however the NMDA is also voltage gated.
Protein channels that are sensitive to electricity are known as WHAT channels?
Voltage Gated channels
Are gated channels are always open?
Yes, it can a gated ion channel is opened when a signal molecule binds to a receptor protein causing the receptor protein to open the ion channel through the cell membrane and after this process the ion channel is closed once again to prevent various molecules to enter the cell.
Describe gating mechanism existing in channels?
G protein-gated ion channels are specific ion channels located in the plasma membrane.
What is a stimulus gated channel?
There are voltage-gated ion channels and ligand-gated ion channels, and since both are stimuli the term stimulus-gated is a redundancy.
What is the speed limit in a typical gated gated community?
25
Why are G-protein-gated ion channels called the shortcut pathway?
All action of neurotransmitter is eventually (mostly) manifest in the regulation of ion in nerve cell, to decide when to fire or not an action potential. Regulation of ion utilize the ion channel, and there are three (known) mechanism which affect the opening and closing of an ion channel : 1) direct influence - ion channel which is directly activated by neurotransmitter attached to them, this one is called ¨Transmitter Gated Channel¨ 2) shortcut pathways - ion channel which is activated by G-protein, this is called the ¨G-protein-gated ion channels¨ 3) second messenger cascades - G-protein trigger a chain reaction of chemical through enzyme or other class of protein and finally affect the opening and closing of ion channels
What is a gated channel?
It is a channel through a membrane that can be opened or closed by chemical or electrical events.
How did the Sumerians solve the problem of flooding?
They used gated ditches and leaves.
Are there any gated comminities in Vail, CO?
Yes, there are many gated comminities in Vail, CO. To find homes in gated communities, visit www.trulia.com, www.realtor.com, and www.homes.com.
Does No Trespassing have to be posted in a private gated community in Florida?
No, its a class a misdemeanor to enter a Gated community...
