Detailed explanation-1: -Answer is (1) Enzymes are non-specific for a reaction and substrate.
Detailed explanation-2: -So, the correct answer is ‘Enzymes are used up in reactions’.
Detailed explanation-3: -Answer and Explanation: The correct answer is (b) An active site is normally hydrophilic in nature. The active site of an enzyme is the location, typically a hollow hole or cleft in the enzyme’s surface, where reactants bind and are converted to substrates.
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: -Optimum temperature is different. Hence the given statement, all enzymes have same intrinsic temperature is incorrect. It is not true.
