Question

Identify the phrases that correctly apply to how specificity determines receptor-ligand interactions. Select all that apply.

* allows receptors to recognize only a signal that they are made for

* allows receptors to form non-covalent bonds with messenger molecules

* relies on molecular fit between two molecules

* allows receptors to distinguish between very similar molecules

* in simple words it is just a strength of ligand binding

is a measure of strength of binding

determines which type of ligands will bind to a receptor

Answer 1

• allows receptors to recognize only a signal that they are made for
• relies on molecular fit between two molecules
• allows receptors to distinguish between very similar molecules
• in simple words it is just a strength of ligand binding
• is a measure of strength of binding
• determines which type of ligands will bind to a receptor

Receptor specificity determines how the receptor prefers a specific ligand over others. It is a measure of affinity between ligand and its receptor, similar to enzyme-substrate interaction. It is dependant upon the binding affinity of ligand to the receptor.
