A gated protein is a protein that can open or close a gate in a cell membrane, regulating the flow of ions or molecules across the membrane. This process allows for the selective transport of specific substances in and out of cells, contributing to cellular function and signaling.

Does protein contain nitrogen?
Yes, protein molecules contain nitrogen atoms in addition to carbon, hydrogen, and oxygen. Nitrogen is an essential component of amino acids, which are the building blocks of protein.
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.
Are gated channels are always open?
No, gated channels are not always open. Gated channels typically require some form of authorization or access control before allowing entry, such as a password, permission, or verification process. This helps to restrict access to authorized users only.
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.
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.
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?
G-protein-gated ion channels are sometimes referred to as the "shortcut pathway" because they allow for a faster cellular response compared to G protein-coupled receptors (GPCRs). When activated, these ion channels open quickly and directly allow ions to flow across the cell membrane, bypassing the traditional GPCR signaling cascade, which can be slower.
How did the Sumerians solve the problem of flooding?
They used gated ditches and leaves.
