A) 2
B) 6
C) 0
D) 12
Correct Answer: D
Solution :
In \[{{C}_{4}}\] plants every \[C{{O}_{2}}\] molecule has to be fixed twice, so, these plants are needed more energy for the synthesis of hexose sugar molecules than C3 plants in which \[C{{O}_{2}}\] has to be fixed only once. 18 ATP molecules are required by \[{{C}_{3}}\] plants for the synthesis of one molecule of hexose sugar while 30 ATP molecules are needed by the \[{{C}_{4}}\] plants for the same. Thus \[{{C}_{4}}\] plants have a need of 12 ATP molecules extra than \[{{C}_{3}}\] plants for the synthesis of one molecule of hexose sugar.You need to login to perform this action.
