The process of stabilizing the structure of an enzyme in its active form by the binding of a molecule outside the active site is an example of ALLOSTERIC ACTIVATION.
Explanation: This is the process by which the binding of one molecule to a larger molecule
enhances the attraction between substrate molecules and other binding sites.
Example of allosteric activation is when oxygen molecule binds to haemoglobin to form oxyhaemoglobin where the oxygen is both the substrate and the effector.
The part of the phospholipid molecule that will face the water, as it is labelled to be hydrophilic would be the polar phosphate group. The correct response would be A.
