Current Question (ID: 13965)

Question:

The steps in catalytic cycle of an enzyme action are given in random order I. The enzyme releases the products. Now enzyme is free to bind another substrate II. The active sites, now in close proximity of substrate break the bond of substrate and E – P complex forms III. Binding of substrate induces the enzyme to alter its shape fitting more tightly around the substrate IV. The substrate binds to the active site of enzyme (i.e., fitting into the active site). The correct order is

Options:

1. I, II, III, IV
2. IV, III, II, I
3. I, III, II, IV
4. I, II, IV, III

Solution:

The correct order of steps in the catalytic cycle of an enzyme action is: IV. The substrate binds to the active site of enzyme (i.e., fitting into the active site). III. Binding of substrate induces the enzyme to alter its shape fitting more tightly around the substrate. II. The active sites, now in close proximity of substrate break the bond of substrate and E – P complex forms. I. The enzyme releases the products. Now enzyme is free to bind another substrate.
