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

No, enzymes are not used up during the reactions they catalyze. Instead, they facilitate the reaction by lowering the activation energy, allowing substrates to convert into products more efficiently. After the reaction, enzymes remain unchanged and can be reused multiple times. This characteristic makes enzymes effective catalysts in biological processes.
Enzymes are biological catalysts. A catalyst speeds up a reaction by lowering the activation energy required. In other words a catalyst offers an alternative pathway to increase the rate of reaction- it is not consumed during a reaction, or affected.
Reactions are speed up by enzymes. Enzymes are type of proteins
biological catalysts known as enzymes are molecules that lower the amount of energy required to kick start a reaction and are NOT used up or changed in the reaction.
no
Enzymes aren't used up or denatured after they catalyse a reaction.
Enzymes remain unchanged and available to catalyze multiple reactions. They are not used up in a reaction.
Correct. Enzymes help to speed up chemical reactions. They may speed them up, costing them some energy, but they are never used up.
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.
Enzymes function by lowering the activation energy needed for a chemical reaction to occur, which speeds up the reaction. They achieve this by providing an alternative pathway for the reaction to proceed more easily. Enzymes do not get consumed in the reaction and can be used repeatedly.
It speeds up the reaction time.
No, enzymes are not consumed in a reaction. Instead, they facilitate and speed up chemical reactions by lowering the activation energy required for the reaction to proceed. Enzymes remain unchanged and can be used repeatedly.
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.
