The primary function of the chloroplasts in a plant is to convert light
from the sun into glucose and energy in a process that is known as
photosynthesis. This energy is then used by the plant cells for
incredibly important functions such as growth and repair, so the chloroplasts are amongst the most necessary parts of any plant.
Answer:
X is negative heterotropic modulator
Explanation:
In allosteric regulations, modulators are molecules that causes a change in the conformation of an enzyme, hence, resulting a change in enzyme activity. It can lead to a decrease or an increase of the enzyme. When a molecule decreases the enzyme activity it called a negative modulator, when it increases or activates the enzyme activity, it is called a positive modulator.
A positive or negative modulator can either be homotrophic (substrate acts as modulator) or heterotropic (another ligand acts as modulator).
In the example above, X is negative heterotropic modulator, because the modulator is different from the substrate and it also decreases the enzyme activity.
