Inactivation of a cell-surface receptor depends on: the activity of phosphatases in the cytosol. the release of the ligand from the receptor ligand binding site. the concentration of ligand surrounding the cell. the binding affinity of the receptor.

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Inactivation of a cell-surface receptor depends on the release of the ligand from the receptor ligand binding site. This ultimately implies that, the concentration of ligand surrounding a cell, as well as the binding affinity of the receptor significantly affects the inactivation of a cell-surface receptor such as receptor kinase.

The inactivation of a cell-surface receptor depends on solely the concentration of ligand surrounding the cell.

A ligand which has the ability to bind to and alter the function of the receptor that triggers a response is called a receptor agonist. On the other end, ligands that bind to a receptor but fail to activate the response are receptor antagonists.

Ligand cell

ligand is 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.

Futthermore, molecules such as hormones and drugs that bind to a receptor are called ligands. The binding can be specific and reversible.

A ligand may activate or inactivate a receptor; activation may increase or decrease a particular cell function
