Beginning with the addition of a carbon dioxide molecule in the Calvin cycle, order these events in photosynthesis:

a) Rubisco combines with RuBP to form 3PGA.
b) ATP and NADPH are used to form G3P.
c) G3P is used to regenerate RuBP.
d) G3P is used to produce glucose.

Answer :

Final answer:

The Correct option is b) ATP and NADPH are used to form G3P.In photosynthesis, ATP and NADPH are used to form G3P, which is then used to produce glucose or regenerate RuBP. Rubisco combines with RuBP to form 3PGA as part of the Calvin cycle.

Explanation:

The correct option is b)ATP and NADPH are used to form G3P. Beginning with the addition of a carbon dioxide molecule in the Calvin cycle, order these events in photosynthesis:

  1. b) ATP and NADPH are used to form G3P.
  2. d) G3P is used to produce glucose.
  3. c) G3P is used to regenerate RuBP.
  4. a) Rubisco combines with RuBP to form 3PGA.
