(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.

Text Solution

Verified by Experts

(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)`
