Depending on the exact response, the substance is generally called a pathogen, yet more specifically depending on the nature of the response and origin of the substance, could be an antigen, allergen, carcinogen, etc.
Some biodrugs like IFNa. Also vaccines, viruses, bacteria, parasites and some toxins. Basically certain biodrugs and most things recogniesd as foreign.
Any 'foreign' protein usually from a microorganisms when entered in body via par-enteral route provokes an immune response from body. Some times complex carbohydrates also do so.
An antigen (any foreign protein).
An antigen.
An antigen
There is an activation of a specific gene by a growth factor.
In some diseases, the immune system inappropriately triggers a response when there are no foreign substances to fight off. The immune system causes damage to its own tissues. The body responds as if the tissues are infected or abnormal.
The molecule that binds to myosin, which causes it to disconnect, is an ATP molecule
stimulus
Enzymes are often substrate-specific, meaning they will only catalyze a reaction with a certain molecule. The difference in structure between amylose and amylopectin causes amylase to catalyze one and not the other.
A stimulus is an external event or cue that triggers a reaction in an organism, while a response is the specific reaction or behavior that follows the presentation of a stimulus. In simpler terms, a stimulus is something that causes a response.
There is an activation of a specific gene by a growth factor.
A stimulus is a change in an organism's surroundings or body which causes it to respond. Hence, a response is an organism's reaction to a specific stimulus.
A stimulus is a factor that causes a response in an organism.
All molecule can react.
An antigen is a foreign body. It is used as a "template" to begin an appropriate immune response.

As close as I can tell, chromopore is either a misspelling of the word 'chromophore' which is the specific part of any molecule that causes color. A second alternative is chromopore is talking about the entire molecule, not just the part that produces the color.
An action causes a reaction. This is also referred to as cause and effect in some areas.
receptor proteins bind to signal molecules
