enzymes are not changed when they perform their function. this means that the same enzyme molecule can be used over and over again.
Yes, however the enzyme returns to its original shape in order to accept the next substrate and be reused.
No, enzymes are neither changed or destroyed in a chemical reaction. The lower the activation energy of reactions, but are not changed by the reaction.
The enzyme can be altered transiently, but overall, the enzyme is the same at the end of the reaction as it was at the beginning.
Yes, but always reversibly.
Enzymes are not a product or reactant, they just make it easier for the reaction to happen. If they are changed, they are part of the reaction, and not enzymes.
No, enzymes are not permanently changed in the chemical reactions they are involved in. Enzymes are catalysts that facilitate chemical reactions by lowering the activation energy, and they remain unchanged after the reaction takes place. They can be used repeatedly in multiple reactions.
Usually enzymes have the role to catalyse a reaction. That means they aren't changed at all, but they influence the mechanism to reduce the activation energy (the energy needed for the reaction). The reaction is therefore performed more easily. To put it very simply: It speeds up a chemical reaction.
Enzymes that enter a reaction do not change in any way but the substrate does.
yes, enzymes are reusable.

Yes, because they are not changed by the reaction.
No. Enzymes are not permanently changed in the chemical reactions in which they are involved. After the reaction, they regain their original shape and are free to catalyze another of the same reaction.

Nothing. The enzyme is not changed by the process of lowering the activation energy of the reaction with the substrates. In their active site some enzymes just give two substrates a protected area for a reaction, some stress bonds thus causing a reaction and some preform catabolically within their active site using their R groups. Regardless of the enzymes activity it is not changed and goes on to perform many processes in the cell.
The reaction rate is affected by enzymes.
the more enzymes, the faster the reaction
Enzymes speed up a reaction but they are not changed by the reaction. They are a protein molecule that helps other organic molecules enter into chemical reactions with one another but is itself unaffected by these reactions. In other words, enzymes act as catalysts for organic biochemical reactions.
