When a ligand is released, what prevents all of the cells in the body from being affected?

a)There is only one receptor for the ligand to bind to

b)The ligand can only bind to a certain cell-receptor at a specific time

c)The shape of the receptors allow specific ligands to bind to it in order to carry out specific functions

d)The ligand never reaches the receptor

When a ligand is released, what prevents all of the cells in the body from being affected is The corresponding shape of the ligand and the receptor allows for specificity. For example, receptors for immune ligands would be found on the target immune system cells and not on cardiac muscle cells or skin epithelial cells. Thus, even though the cardiac muscle cells or skin epithelial cells would be exposed to immune ligand , they would not be able to bind to it and therefore could not react to it.

The shape of the receptors allows specific ligands to bind to it in order to carry out specific functions, thereby preventing all of the cells in the body from being affected (Option c).

A ligand can be defined as any specific molecule (e.g., a hormone) that interacts with its molecular target (e.g., a protein receptor) to trigger a signaling pathway.

Some of the most common types of ligands include activators, lipids (steroids), substrates, inhibitors, neurotransmitters, etc.

Each specific ligand binds to its corresponding receptor localized on the cell surface or in the cytoplasm.

When a ligand interacts with its corresponding receptor, a change in the tridimensional conformation of the ligand occurs and it triggers specific cellular pathways.

In conclusion, the shape of the receptors allows specific ligands to bind to it in order to carry out specific functions, thereby preventing all of the cells in the body from being affected (Option c).
