Answer:
D. Allosteric activator
Explanation:
In an enzyme, the allosteric site is a site/motif different from the active site, (i.e., the site with catalytic activity) which is able to interact with regulatory effector molecules in order to activate or inhibit enzymatic activity by influencing the tridimensional (3D) structure of the enzyme. An allosteric activator is an effector molecule with the ability to bind to a specific enzyme at a different site than the active site, thereby modifying the shape of the enzyme and increasing the affinity of this enzyme for its substrate. Moreover, Adenosine monophosphate (AMP) is a nucleotide composed of a phosphate group, a sugar ribose, and an Adenine (A) base. This effector molecule (AMP) has shown to allosterically stimulate diverse enzymes in physiological conditions (e.g., AMP-activated protein kinase).

Answer:
The correct answer is option - chondrosis: freely moving joint.
Explanation:
Chondroitin is the condition, not a joint which is basically is the loss or softness of the smooth cartilage that covers the joint of the knee at the back of the kneecap. This condition occurs due to prior injury, overweight or obesity, and a more common cause is an acceleration of the cartilage abnormally at the kneecap.
It is also known as cartilage deterioration which is joint effusion. All three joints are correctly matched. amphiarthrosis is a slightly movable joint, synarthrosis is an immovable joint, and gomphosis is a joint that articulation between tooth and bone.
Thus, the correct answer is option - chondrosis: freely moving joint.
Because nowadays, many horses are domesticated, and food they would have eaten in the wild, they don't usually eat anymore. They have learnt to adapt to eating other foods, like hay, that require molars to ingest. This is why over time, their tooth structure has changed.
