In the lock and key model of molecular structure, what term is used for the "key" molecule?
A) The antigen
B) The antibody
C) The antibacterial
D) The antibiotic
Lock And Key Model
A model for enzyme-substrate interaction suggesting that the enzyme and the substrate possess specific complementary geometric shapes that fit exactly into one another.
Molecular Structure
The three-dimensional arrangement of atoms within a molecule, determining its chemical properties and behavior.
Antibody
A protein produced by the body's immune system that recognizes and binds to foreign substances such as bacteria and viruses, neutralizing them.

Final Answer :
A
Explanation :
The "key" molecule in the lock and key model of molecular structure is referred to as the antigen. This model is often used to describe how enzymes and substrates interact, where the enzyme is the "lock" and the substrate is the "key." However, in the context of immunology, the antigen can be seen as the "key" that fits into the "lock" of the antibody, initiating an immune response.
