For most ligand-receptor complexes, binding is favored.

Detailed explanation-1: -Cellular receptors are proteins either inside a cell or on its surface which receive a signal. In normal physiology, this is a chemical signal where a protein-ligand binds a protein receptor. The ligand is a chemical messenger released by one cell to signal either itself or a different cell.
Detailed explanation-2: -Within biochemistry, a ligand is defined as any molecule or atom that irreversibly binds to a receiving protein molecule, otherwise known as a receptor. When a ligand binds to its respective receptor, the shape and/or activity of the ligand is altered to initiate several different types of cellular responses.
Detailed explanation-3: -01) Which of the following statements is not true about a ligand gated ion channel receptor? Feedback: Ligand gated ion channels consist of five glycoproteins and not six. The other statements are correct. Receptors that are controlled by the membrane potential are known as voltage gated ion channels.
Detailed explanation-4: -A ligand is a molecule that binds another specific molecule, in some cases, delivering a signal in the process. Ligands can thus be thought of as signaling molecules. Ligands interact with proteins in target cells, which are cells that are affected by chemical signals; these proteins are also called receptors.
