|
|
Enzymes are composed of polypeptide chains.
|
|
|
Enzymes form a temporary association with a reactant.
|
|
|
Enzymes are destroyed when they are used and must be synthesized for each reaction.
|
|
|
Enzymes are specific because of their shape and catalyze only certain reactions.
|
Detailed explanation-1: -Hence option (A), (B)and (D) are correct about enzymes. So, the correct answer is Option C. Note: Enzymes are only used to catalyse the reactions associated with an organism’s body and one enzyme cannot catalyse more than one reaction due to their high specific nature.
Detailed explanation-2: -The enzyme is not destroyed during the reaction and is used over and over. A cell contains thousands of different types of enzyme molecules, each specific to a particular chemical reaction.
Detailed explanation-3: -Enzymes do not alter the overall change in free energy for a reaction. 2.
Detailed explanation-4: -Enzymes are mostly proteins that catalyze various biochemical reactions. The catalytic reaction occurs through a specific region of the enzyme called the ‘active site’. Enzymes are not destroyed after the reaction. They remain unaltered after the product is released.
