What else can I help you with?
Does protein contain nitrogen?
yesEvery protein should contain Nitrogen.To be a protein it should contain -NH2 gruop
If you replace all the oxygen atoms in a protein with sulfur atoms what will happen to the protein?
Replacing all the oxygen atoms in a protein with sulfur atoms can disrupt the structure and function of the protein. This substitution may lead to changes in the protein's folding, stability, and interactions with other molecules, potentially causing loss of function or functional changes.
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?
This protein molecule is likely an enzyme, which facilitates the chemical reaction by lowering the activation energy required for the reaction to occur. Enzymes remain unchanged after the reaction and can be reused to catalyze multiple reactions. They are specific to the reaction they catalyze and are essential for the proper functioning of the cell.
What is the chemical formula for hydrolyzed soy protein?
The chemical composition of hydrolyzed soy protein can vary depending on the degree of hydrolysis, but it is primarily composed of amino acids and small peptides. Therefore, there is no single chemical formula for hydrolyzed soy protein.
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.
How can a gated channel protein be opened to allow the passage of molecules?
A gated channel protein can be opened by specific signals or changes in the cell environment, such as binding of a molecule or changes in voltage. This triggers the channel to change its shape, allowing molecules to pass through.
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.
Protein channels that are sensitive to electricity are known as WHAT channels?
Protein channels that are sensitive to electricity are known as voltage-gated ion channels. These channels open and close in response to changes in the membrane potential, allowing specific ions to flow across the cell membrane and generate electrical signals.
What is a gated channel?
A gated channel is a protein channel in a cell membrane that can open or close to allow specific ions, like sodium or potassium, to pass through. The opening and closing of these channels are controlled by certain signals, like changes in voltage or the binding of specific molecules, in order to regulate the flow of ions into and out of the cell.
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.
Ion channels that can be opened by physiological stimuli are said to be?
ligand-gated or voltage-gated ion channels.
What is the speed limit in a typical gated gated community?
25
What structures in the cell membrane function as ion channels?
Proteins such as ion channels embedded in the cell membrane function as gateways for specific ions to enter or exit the cell. These ion channels can be voltage-gated, ligand-gated, or mechanically-gated, regulating the flow of ions in response to changes in membrane potential, binding of specific molecules, or mechanical stimuli, respectively.
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 the difference between voltage-gated and ligand-gated ion channels in terms of their mechanisms of activation and regulation?
Voltage-gated ion channels are activated by changes in membrane potential, while ligand-gated ion channels are activated by binding of specific molecules (ligands). Voltage-gated channels open in response to changes in electrical charge across the membrane, whereas ligand-gated channels open when a specific molecule binds to them. Additionally, voltage-gated channels are regulated by membrane potential, while ligand-gated channels are regulated by the presence of specific ligands.
