Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is a correct statement on the state of an enzyme at the conclusion of a chemical reaction?
A
The products of the reaction never release themselves from the enzyme
B
The enzyme is dissolved by the substrate that covers it during the reaction
C
The enzyme is not changed by the chemical reaction
D
The chemical reaction causes the enzyme to reduce in size
Explanation: 

Detailed explanation-1: -In conclusion, an enzyme is unchanged by the chemical reaction it catalyzes (speeds up).

Detailed explanation-2: -So, the correct answer is ‘They are all proteins except ribozymes.

Detailed explanation-3: -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-4: -This statement about enzymes is true: Enzymes accelerate reactions by lowering the activation energy. Enzymes are proteins whose three-dimensional form is key to their function. Enzymes do not alter the overall change in free energy for a reaction.

Detailed explanation-5: -The correct answer: The statement that is false about the enzymes d. A specific enzyme can catalyze a variety of chemical reactions. The enzymes are basically proteins that are produced from the secretory cells.
