Yes. They are disassembled into amino acids that are themselves fully reusable.
No.
yes
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.
The Reaction Rate
Yes,enzymes speed up metabolic reaction in organisms.
an enzyme does not get used up in a reaction. it is essentially a catalyst. although an enzyme speeds up the rate of chemical reactions by decreasing the amount of activation energy required, it does not in itself change during the reaction.***Note:: Enzymes cease to function when they denature. This usually occurs by pH level changes, or increased temperatures. This occurs because it causes the bond of the molecule to break and essentially changes the shape of the enzyme. Because an enzyme is a lock and key model, when the shape changes it becomes uselesssources: my brain
No that is false. Enzymes do NOT increase number of collisions in a chemical reaction.
no
Enzymes lower the activation energy of a chemical reaction. Since more molecules have sufficient energy to react, the reaction occurs faster.
While the structure of an enzyme can, and often does, change over the course of a reaction, after a reaction has completed, enzymes are returned to their starting state. It is worth noting that certain cofactors (such as ATP or GTP) may also need to be replaced in order for the reaction to procede again.

The reaction rate is affected by enzymes.
the more enzymes, the faster the reaction
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.
Enzymes are biocatalysts, they accelerate the reaction rate. Different individual enzymes operate by different mechanisms.
Enzymes have no effect on the overall thermodynamics of a reaction.
its an enzyme enzymes are a type of protein
Biocatalysts usually are very specific to the reaction that they catalyze. So many only speed up one reaction. Quite often a chain reaction occurs where numerous enzymes catalyze reactions at different points speeding up a process that would take much longer and propelling the reaction through numerous phases.
Enzymes speed up biochemical reactions by lowering the activation energy of the reaction.
