Question

Which of the following statements concerning the light-independent processes of photosynthesis is true? 1Points A Carbon dioxide is removed as a waste product. B An unstable six carbon molecule is created. C No energy is produced. D All of the glucose-creating molecules made from the processes go into making glucose.

Answer 1

The correct answer is option D

Reason: All other options are incorrect as

Carbon dioxide used in the light-independent processes of photosynthesis (Celvin Cycle) are used completely to form glyceraldehyde-3-phosphate (G3P) molecule which is stable and is a six carbon molecule. Also Energy is produced in the form of NADPH and ATP.

6 CO2 enters the celvin cycle and 6 G3P molecules are formed out of which 1 leaves the cycle and and rest 5 G3P molecules get regenerated thereby regenerating 33 RuBP acceptor molecules.
