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 useless

∙ 15y agoNo. That is the definition of a catalyst (which enzymes are) - not being used up in a reaction.

∙ 13y agoNo. Enzymes are not used up in reactions, as with all catalysts. They lower the activation energy and speed up reaction rate.

∙ 9y agoNo. By definition, they are not used up. They help by making the reaction faster.

Enzymes are not consumed or altered by the chemical reactions they catalyze. They can be used repeatedly and are not changed in the process. Once the reaction is complete, enzymes are released unchanged and available to catalyze more reactions.
Reactions are speed up by enzymes. Enzymes are type of proteins
Enzymes are used in almost every biological reaction that takes place in an organism to expedite the process.
No, enzymes are not consumed or altered in the reaction they catalyze. They remain unchanged and can be used repeatedly.
no
Enzymes aren't used up or denatured after they catalyse a reaction.
Enzymes lower the activation energy of a reaction, acting as a catalyst and speed up the reaction. Plus they never get used up, only over and over again.
It speeds up the reaction time.
Enzymes act as catalysts. They speed up the reaction time.
Yes. Enzymes are catalysts and as such they participate in the reaction without being used up.
Enzymes are catalysts in a chemical reaction, they are used in chemistry to increase the speed of a specific chemical reaction. A single enzyme will not speed up multiple chemical reactions, usually it is limited to one reactant.
Actually, enzymes are typically used to catalyse a biological reaction, leading to a faster reaction rate, not slower.
they speed up the reaction.
enzymes are used in textiles to prepare fabrics before they are woven. They reduce impurities. They are often used in dying fabrics to reduce rinsing time. Using enzymes replace harsh chemicals which aren't environmently friendly. This is because enzymes are biological catalysts - this means they speed up reactions and aren't used up in the reaction, unlike chemicals.
