| Consider the following statements. |
| I. Calvin cycle is known as \[{{\operatorname{C}}_{3}}-cycle\]. |
| II. \[{{\operatorname{C}}_{3}}-plants\] have Kranz type of leaf anatomy. |
| III. \[C{{O}_{2}}\] fixation in \[{{\operatorname{C}}_{3}}-plants\] is done through 3PGA. |
| IV. \[{{C}_{4}}-\,plants\] show more photorespiration as compared to \[{{\operatorname{C}}_{3}}-plants\], resulting in higher production of dry matter. |
| Which of the statements given above are correct? |
A) I, II and III
B) I, III and IV
C) I and III
D) II and IV
Correct Answer: C
Solution :
Calvin cycle is known as \[{{C}_{3}}\] cycle because \[C{{O}_{2}}\] reduction in cyclic process and first stable product in this cycle is a 3-C compound (i.e. 3 - phosphoglyceric acid or 3 -PGA).
