Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Once a new product leaves an enzyme, the enzyme is unchanged and ready for the next substrate. What is this called?
A
reusable
B
catalyst
C
specific
D
fragile
Explanation: 

Detailed explanation-1: -Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction.

Detailed explanation-2: -Once a new product leaves an enzyme, the enzyme is unchanged and ready for the next substrate. What is this called? reusable. What is a substance called if it speeds up a chemical reaction? catalyst.

Detailed explanation-3: -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.

Detailed explanation-4: -A process called catalysis happens. Catalysis is when the substrate is changed. It could be broken down or combined with another molecule to make something new. It will break or build chemical bonds. When done, you will have the enzyme/products complex.

Detailed explanation-5: -Specificity is a property of the enzyme and describes how restrictive the enzyme is in its choice of substrate; a completely specific enzyme would have only one substrate.
