Which of the following molecule is NOT needed for the Calvin Cycle to take place? a. H2O
b. CO2
c. RuBP
d. NADPH
(5C enzyme)

H2O is not needed for Calvin cycle to take place.

Option A is the correct answer.

Calvin cycle is the cycle that take place during photosynthesis and it is light depend where Co2 enters the pores of the stomata of the leaf.

It is in three stages.

1. Carbon fixation: Co2 react with with three molecules of the five carbon acceptor molecule (RuBP) to produce ,three molecules of carbon compounds that divide to form three carbon compound (3-PGA) in the presence of rubisco enzyme.

2. Reduction stage: In this stage,6 ATP and 6 NADPH convert six 3-PGA molecules to 6 molecules of three-carbon sugar (G3P). It is a reduction reaction because NADPH lose electrons to a three-carbon intermediate to produce G3P.

3. Regeneration : G3P molecule move to produce glucose, five G3Ps are recycled to produce the RuBP acceptor. This reaction requires ATP.

Therefore, H2O is not included in Calvin cycle.

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.
