Signal Transduction
The molecule that can bind to a receptor protein is called a ligand.
A channel linked receptor transduces functions of the same protein molecule. An example of a channel linked receptor are neurotransmitters in the brain.
The most important factor determining which type of receptor a signal molecule will bind to is the specificity between the shape of the signal molecule and the complementary binding site on the receptor. Additionally, the affinity of the signal molecule for the receptor and the presence of any co-factors or co-receptors can also play a role in determining the binding specificity.
An aceticoceptor is a part of a molecule which acts as a receptor for acetyl groups.
G-proteins are regulatory proteins associated with membrane-bound receptor molecules. They facilitate signal transduction by relaying messages from activated receptors to other intracellular signaling components.
A molecule such as a neurotransmitter or hormone that binds to a receptor is called a ligand. This binding triggers a biological response in the target cell, influencing its function.

Intracellular receptor
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.

acts as catalysts
The glycoprotein CD4 is a co-receptor. A co-receptor is "a cell surface receptor, which, when bound to its respective ligand, modulates antigen receptor binding or affects cellular activation after antigen-receptor interactions." (MediLexicon)
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.
to detect stimulus
Proteins can cover the binding site of a receptor and prevent another molecule from binding to it. This interaction can inhibit the receptor's activity and affect cellular signaling pathways.
