The catalytic cyclic of an enzyme action is described as:
1. \(\mathrm C \rightarrow \mathrm B \rightarrow \mathrm A \rightarrow \mathrm D\)
2. \(\mathrm{C} \rightarrow \mathrm{B} \rightarrow \mathrm{D} \rightarrow \mathrm{A}\)
3. \(\mathrm B \rightarrow \mathrm C \rightarrow \mathrm D \rightarrow \mathrm A\)
4. \(\mathrm D \rightarrow \mathrm C \rightarrow \mathrm A \rightarrow \mathrm B\)
| A. | Enzyme releases products of the reaction and gets free. |
| B. | Substrate induces the enzyme to alter its shape. |
| C. | The substrate binds with the active site of the enzyme. |
| D. | Enzymes-product complex is formed. |
2. \(\mathrm{C} \rightarrow \mathrm{B} \rightarrow \mathrm{D} \rightarrow \mathrm{A}\)
3. \(\mathrm B \rightarrow \mathrm C \rightarrow \mathrm D \rightarrow \mathrm A\)
