In the Calvin Cycle, how many ATP molecules are required to regenerate RuBP from 5 G3P
molecules?
3 ATP molecules.
How many CO2 molecules must be added to RuBP to make a single molecule of glucose?
6 CO2 molecules, which produce two G3P molecules that can combine to
make 1 glucose.
After 3-PGA is phosphorylated, it is reduced by what?
NADPH, it supplies the electrons that reduce the 3 -PGA post-
phosphorylation.
Carbon fixation involves the addition of CO2 to what?
RuBP.
What reaction ensures that the Calvin cycle can make a continuous supply of glucose?
Regeneration of RuBP, since it fixes CO2 into an organic molecule that is
used to produce sugar.

How are the light-dependent and light-independent reactions related?
The light-dependent reactions produce ATP and NADPH, which are then
used by the light-independent reactions.
What is the biological significance of the light-independent reactions of photosynthesis?
They convert CO2 to sugar, and all organisms use this sugar to generate
energy.
What is the primary product of Photosystem I?
NADPH, used to supply energy for the production of sugars during
photosynthesis.
What happens in the light-dependent reactions of photosynthesis?
H2O molecules are split to replenish electrons in photosystem II, leaving
behind protons which are used to generate a gradient for ATP formation.
Oxygen is released as a byproduct.
What is the importance of the light-independent reactions in terms of carbon flow in the
biosphere?
