As compared to a `C_(3)` plant, how many additional molecules of ATP are needed for net production of one molecule hexose sugar by `C_(4)` plantsA. 2B. 6C. 12D. zero |
|
Answer» Correct Answer - C In `C_(4)`- plants every `CO_(2)` molecule as to be fixed twice, so these plants are needed more energy for ` C_(3)`-plants in which ` CO_(2)` has to be fixed only once. 18 ATP molecules are required by `C_(3)`-plants for the synthesis of one molecule of hyexose 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. |
