An enzymes structure is not affected by a reaction. The enzyme has the same structure at the end of the reaction as it did before it took place. Note: Enzyme structures may change during the reaction itself but will return to their original shape etc when the reaction is complete.
amylase
Yes, because it is a characteristic of a chemical reaction.
This is a photochemical reaction of decomposition: silver (black) is released.
No. The essence of a chemical reaction is the alteration of the chemical structure of the substance. The reaction that allows for the substance to keep their properties is the physical reaction.
Yes, if the allergic reaction causes a disruption to the integrity of the membrane or structure, you can develop a secondary bacterial or viral infection of the area. I had this happen to me - I had an allergic reaction to a chemical in chemistry class on the outside of my ear and developed a secondary bacterial infection that I had to take antibiotics for.
The doctor observed the patient's reaction.Question. is the bold words a subject or a predicate?
A chemical reaction is observed.
subject
"Observed the patient's reaction" is a predicate. A suitable subject would be "The doctors", "the nurse", or "the researchers."

a fight-or-flight reaction.
amylase
The percent yield of a reaction measures the efficiency of a reaction. The relationship of the actual yield to the theoretical yield is used to determine this.
Reaction distance is the distance a vehicle will travel before the operator can react to what is observed. This distance will vary depending on the speed of the vehicle. The reaction distance is actually the reaction time of the operator.
That depends on what you mean? Do you mean the relationship or reaction between the characters or the general reaction from the readers?
