To accept the ligand that properly fits the receptor sit. Then the G protein is activated and GDP is phosphorylated to GTP and the protein goes on to begin signal transduction in one of several ways open to G proteins.
What else can I help you with?
A protein on the cell membrane binds and recognized to specific substance is called a?
It is called a receptor protein.
Why G protein linked receptor is called as G protein linked receptor?

What is the molecule called that can bind to a receptor protein?
The molecule that can bind to a receptor protein is called a ligand.
What is the difference between a ligand and a receptor protein?
A ligand is a molecule that binds to a receptor protein, while a receptor protein is a protein that recognizes and binds to specific ligands, triggering a biological response. Simply put, a ligand is like a key that fits into a receptor protein like a lock, initiating a signaling cascade in the cell.
What occurs when a receptor protein is coupled with an ion channel?
Changes in permeability occur when a receptor protein is coupled with an ion channelchanges in permeability
What is the difference of g-protein receptor system and tyrosine kinase receptor?
Receptor tyrosine kinases do not require the use of second messengers while G protein-coupled receptors need.
What is the job of a receptor?
The job of a receptor protein is to receive chemical signals from outside the cell.
The outer part of G protein receptor binds and its inner part binds?
The outer part of a G protein-coupled receptor (GPCR) binds to ligands, such as hormones or neurotransmitters, which activates the receptor. The inner part of the receptor interacts with and activates a G protein, initiating downstream signaling cascades within the cell.
What is the job of the receptor proteins?
The job of a receptor protein is to receive chemical signals from outside the cell.
What binds to a signal molecule enabling the cell to respond to the signal molecule?
A receptor protein on the cell membrane binds to the signal molecule, initiating a series of intracellular events that lead to a cellular response. The binding of the signal molecule to the receptor triggers a signaling cascade that ultimately activates specific cellular pathways.
When a receptor protein in a cell membrane acts as a enzyme the receptor protein does what?
When a receptor protein acts as an enzyme, the receptor protein activates a second messenger that acts as a signal molecule within the cell. Resources: HOLT Biology Textbook - 9th grade edition Chapter 4, Cells and Their Environment.
Relationship between receptor protein and signal molecule?
Receptor proteins are molecules on the cell surface or within cells that bind specific signal molecules, such as hormones or neurotransmitters. When a signal molecule binds to a receptor protein, it triggers a cellular response or cascade of events, which can lead to changes in cell function, gene expression, or behavior. This binding is highly specific, as each receptor protein typically recognizes and responds to only a particular type of signal molecule.
