Enzyme function is influenced by physical and chemical environment factors such as pH and temperature.
-Enzymes may require a nonprotein cofactor or ion for catalysis to take place.
-Enzymes increase the rate of chemical reaction by lowering activation energy barriers.
The one that does not describe the relationship between the nucleus and the electron cloud of an atom would be : the mass of the nucleus and electron cloud are balanced.
Ie : The mass of nucleus and electron cloud are always differ from one another

Tryptophan self-controls its synthesis. If we have a large amount of tryptophan in the sense that it exceeds, tryptophan would act as a co-repressor which prevents synthesis of more enzymes for its production. Hope this answers the question.
