Question

True or false, the same enzyme can function in a wide range of conditions like temperature and pH. Select one: a. True b. False What are enzymes? Select one: a. Very specific biological catalysts b. Molecules that lower the activation energy of chemical reactions in cells c. Molecules that are not used up in a chemical reaction, can be reused d. Most are proteins e. All of the above What determines the function of an enzyme? Select one: a. Its unique three-dimensional structure b. How heavy it is c. What organism it came from d. How old it is e. None of these What is it called when a poison blocks the action of an enzyme on its substrate? Select one: a. Modality b. Augmentation c. Bonding d. Upsetting e. Competitive inhibition What is metabolism? Select one: a. Breakdown of substances to yield energy b. Chemical processes within living cell or organism necessary for maintenance of life c. Sum of a chemical reactions in a cell d. All of the above

Explanation / Answer

6) Statement is false, the same enzyme cannot funtion at different temperature and pH. Every enzyme has an optimum conditions like temperature and pH for its proper or best function.

7) Most of the enzymes are proteins(d). Those give rise to the functional product.

8) The function of an enzyme is determined by its unique three-dimensional structure(a). The order of aminoacids make unique shape or structure for every enzymes.

9) The process in which a poison blocks the action of an enzyme on its substrate is called competitive inhibition. Here the enzyme cannot bind to its substrate because the inhibitor poison already bind to the substrate.

10) The metabolism is the sum of catabolism and anabolism in a cell. All the mentioned points are correct (d). It is necessary for he maintenance of life of a living cell.
