Identify the CORRECT combination(s) between the enzymes in Group 1 and the reactions in Group 2 they catalyze.
| Group 1 | Group 2 |
|---|---|
| (P) Superoxide dismutase | (i) Formation of hydrogen peroxide |
| (Q) Phosphoenolpyruvate carboxylase | (ii) Formation of oxaloacetate |
| (R) Ribulose 1,5-bisphosphate carboxylase/oxygenase | (iii) Formation of 3-phosphoglycerate |
| (S) Hexokinase | (iv) Formation of glucose-6-phosphate |
(A) P−iii, Q−ii, R−iv, S−i
(B) P−i, Q−ii, R−iii, S−iv
(C) P−ii, Q−iv, R−i, S−iii
(D) P−i, Q−iii, R−ii, S−iv
Answer
Answer: (B) P−i, Q−ii, R−iii, S−iv
Explanation:
Superoxide dismutase catalyzes the formation of hydrogen peroxide (i), phosphoenolpyruvate carboxylase catalyzes the formation of oxaloacetate (ii), RuBisCO catalyzes the formation of 3-phosphoglycerate (iii), and hexokinase catalyzes the formation of glucose-6-phosphate (iv).
