question_answer1) Assertion : Enzymes have active sites and substrates reactive sites, on their surfaces respectively. Reason : Active and reactive sites push the enzyme and substrate molecules away from each other : [AIIMS 1999]
question_answer2) Assertion : Enzyme substrate complex remains throughout the reaction. Reason : The greater the affinity of the enzyme for a substrate, the higher is the catalytic activity.
question_answer3) Assertion : Desmolysing enzymes are those which catalyse the reactions by hydrolysis. Reason : Digestive enzymes are hydrolysing in nature.
question_answer4) Assertion : Coenzymes are also called prosthetic groups. Reason : Coenzymes and prosthetic groups are cofactors.
question_answer5) Assertion : Enzymes are defined as biological proteins. Reason : Chemically all enzymes are globular proteins. [AIIMS 1997]
question_answer6) Assertion : DNA molecules and RNA molecules are found in the nucleus of cell. Reason : On heating, enzymes do not lose their specific activity. [AIIMS 1994]
question_answer7) Assertion : The higher the turn-over number the more efficient an enzyme is. Reason : It is not dependent upon the number of active sites present over an enzyme.
question_answer8) Assertion : Allosteric enzymes show feed back inhibition. Reason : The inhibitor is competitive.
question_answer9) Assertion : Enzyme becomes inactive below minimum temperature. Reason : The inactivity of the enzymes is due to denaturation.
question_answer10) Assertion : Enzymes lower the activation energy. Reason : A substrate molecule can be acted upon by a particular enzyme.
