Answer:
Ligand-receptor interaction is the first interaction that triggers cell signalling.
Explanation:
Ligands are the hormones, drugs or neurotransmitters that specifically bind with receptors present in cell surface to initiate cell signalling. Ligand binding to the receptor is reversible. Binding of the ligand to the receptor can activate or inactivate receptor. Activation may lead to cell signalling pathways. Inside cells, there are secondary molecules which on activation starts a cascade of reactions. which in-turn regulate the function of the ligand molecule.
Best Choice:
Ligand-receptor interaction is the first interaction that triggers cell signalling.

The correct answer is ionization.
Ionization refers to the procedure by which a molecule or an atom attains a negative or positive charge by losing or gaining electrons to produce ions, usually in combination with other chemical modifications.
Ionization can result due to the loss of an electron after collisions with other atoms, subatomic particles, molecules, and ions, or through the association with electromagnetic radiation.
