During the light-independent reactions of photosynthesis:
G3Ps get rearranged to make 5-carbon sugars with phosphates |
for every three CO2, 7 G3Ps are made |
the main product is 3-phosphoglycerate |
a single glucose molecule can leave the cycle but the rest go back in |
a proton-motive force directly powers reduction of CO2 |
During the light-independent reactions of photosynthesis:
The correct answer is G3Ps get rearranged to make 5-carbon sugars with phosphates
Why not 2) for every three CO2, 7 G3Ps are made: This is incorrect because for every 3 CO2 molecules, 6 G3Ps are made
Why no 3) the main product is 3-phosphoglycerate: This is incorrect because main product is sugare such as glucose
Why not 4) a single glucose molecule can leave the cycle but the rest go back in: This is incorrect, glucose is not reused in the cyle like G3P
Why not 5) a proton-motive force directly powers reduction of CO2: Incorrect proton motive force indirectly powers synthesis of ATP
