a receptor structure in a ligand-gated sodium-ion pore. The receptor is like a cave which is an outer part of a protein structure which also has a tunnel which can be open or closed, and the presence of the neurotransmitter causes the tunnel (pore) to open.
Endocytosis is the bulk transfer of materials from inside to outside of a cell with the help of special vesicles. Types of Endocytosis : 1) phagocytosis 2) potocytosis 3) receptor mediated endocytosis

One of the most common molecules of the cell that transmit information from outside to inside are transmembrane receptors. Typically, a ligand will bind to to exterior portion and trigger receptor activation, leading to downstream signaling within the cell.
The intracellular proteins form the most important class of receptors called receptor proteins. Receptor proteins are located in the cytoplasm, cell membrane, or nuclear membrane. 1. Cytoplasmic receptor proteins include those that respond to steroid hormones. Ligand activated receptors may enter the cell nucleus where they modulate gene expression. 2. Receptors within cell membranes may be peripheral or trans-membrane proteins. Many receptors for hormones and neurotransmission are trans-membrane proteins. - a. Metabotropic receptors are coupled to G-proteins, acting through various secondary pathways involving ion channels, enzymes such as adenylyl (adenylate) cyclases, and phospholipases, or PDZ domains. - b. Ionotropic receptors are ligand-activated ion channels that permit entry of ions when the central pore is open. A receptor protein is protein molecule that found embedded in the plasma membrane surface of a cell. It receives chemical signals from outside the cell.
The molecule that can bind to a receptor protein is called a ligand.
receptor protein and marker protein are differente''marker protein have cell surface marker that act as name together, the identification of different types of cells and the receptor proteins transfer information from the outside of the cell to the inside receptor proteins are like boulders that how it's difference.
yes a ligand is anything that can change the conformation of a receptor protein. hormones bind to proteins in the same way ligands do
Some cell receptor is held with it some proteins that transform the signal when a particular ligand is bind. When a ligand binds to a receptor it results in conformation changes in the receptor. The receptor interact with the other protein attached to it and mediate signal transduction by producing some secondary messengers that's how the signal is amplified and create a respond.... (eg., G -Protein coupled receptor)
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.

There are two receptors that neurotransmitters interact with: ligand-gated receptors or ionotropic receptors and G protein-coupled receptors or metabotropic receptors depending on the neurotransmitter (the ligand). When the ligand binds with the neurotransmitter receptor it causes a sequence of chemical reactions to relay signals.Brought to you by altogenlabs.com
N. Take a G protein linked receptor for an example. The ligand docks and causes a conformational change that causes a G protein to dock with the transmember protein receptor and initiate signal transduction through secondary messengers.
Hormones are ligands that bond to cells and carry a specific receptor. The ligand bonds its receptor to form a complex that acquires a purpose. The ligand triggers a change in the receptor, which activates a potential biological function. Cells that do not exhibit the receptor never receive the signal.
