Which of the following does not occur during the calvin cycle?
a) oxidation of NADPH
b) release of oxygen
c) regeneration of the CO2 acceptor
d) carbon fixation
The correct answer would be (b). Release of Oxygen doesn't occur during Calvin Cycle.
It happens during the Light Reaction Stage of Photosynthesis. An electron is stripped from a water molecule freeing the oxygen and hydrogen atoms. The free oxygen atom then combines with another free oxygen atom to produce oxygen gas which is then released.
Rest three options occur in Calvin Cycle as explained below:

The Calvin Benson cycle use the energy trapped in ATP and NADPH generated by the light reactions to build sugars from CO2. What below is FALSE regarding this sugar-building cycle? Select one: a. Initially RuBP is carboxylated by RuBisCo where atmospheric CO2 is captured and put into the cycle. b. ATP and NADPH generated by the light reactions are used to reduce 3PG to a more energetic/reduced G3P (some of which will be diverted off to build sugar!) c. More...
