What happens to the enzyme after it is detached from the product?

The enzyme will always return to its original state at the completion of the reaction. One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. After an enzyme is done catalyzing a reaction, it releases its products (substrates).

How does an enzyme convert a substrate to a product?

When the substrate fits into the active site of the enzyme, the enzyme catalyses a reaction that breaks the substrate down into the product. The product is then released from the active site and the enzyme remains unchanged, so can catalyse another reaction.

What happens to the enzyme after it’s changed the substrate into a product?

A substrate enters the active site of the enzyme. This forms the enzyme-substrate complex. The reaction then occurs, converting the substrate into products and forming an enzyme products complex. The products then leave the active site of the enzyme.

Can an enzyme be reused after releasing the substrate as a product?

At the end of the reaction, the product/s are formed, the enzyme remains unchanged, can bind another substrate and can be reused many times.

Can enzymes be used over and over again?

Because enzymes are not consumed in the reactions they catalyze and can be used over and over again, only a very small quantity of an enzyme is needed to catalyze a reaction. A typical enzyme molecule can convert 1,000 substrate molecules per second.

Do enzymes change shape after a reaction occurs?

Enzymes speed up reactions. Enzymes interact with specific substrates. False. Enzymes change shape after a chemical reaction.

How does enzyme bind to substrate?

The substrate binds to the enzyme by interacting with amino acids in the binding site. The binding site on enzymes is often referred to as the active site because it contains amino acids that both bind the substrate and aid in its conversion to product. You can often recognize that a protein is an enzyme by its name.

What happens when an enzyme changes shape?

If the enzyme changes shape, the active site may no longer bind to the appropriate substrate and the rate of reaction will decrease. Dramatic changes to the temperature and pH will eventually cause enzymes to denature.

Can change the active site of an enzyme and alter its function?

Increasing the temperature generally increases the rate of a reaction, but dramatic changes in temperature and pH can denature an enzyme, thereby abolishing its action as a catalyst. The induced fit model states an substrate binds to an active site and both change shape slightly, creating an ideal fit for catalysis.
