(a) What is (a) multimolecular colloid (b) macromolecular colloid and (c) associated colloid ? (b) Write the equation for the two steps involved in enzyme catalysis. |

Answer» Solution :(a) If large number of atoms and small molecules aggregate to form particles of colloidal size, then the colloid is multimolecular colloid. Macromolecules (POLYMER) which have colloidal dimension in a suitable medium disperse to form MACROMOLECULAR colloid. Some substances (molecules) of intermediate size at higher concentration aggregate to form colloidal particles. This is ASSOCIATED colloid. (b) Step - 1 `underset("Enzyme substrate")(E+ S) to underset("activated complex")(ES^+)` Step 2 : `ES^(+) to E + underset("Product")(P)` |
