In photosynthesis what are the reactants? What are the
products?
 Write Chemical Notation

What goes into the Light Reactions (Stage 1)? What comes
out?
 Chemicals
There are _____ photosystems and both are located in
____________ membrane.

__________ provides the photosystem with electrons.

Oxygen is made from the splitting of ____________.

Reactants
1.
2.
3.
4.
Products
Chlorophyll (In PS1 & 2) absorbs light
Electrons move down the ETC pulling H+ into
thylakoid & makes NADPH
3. Protons (H+) move through ATP Synthase
enzyme at end of ETC spinning it converting
ADP to ATP
e- are replaced by the splitting of H2O

This creates O2 gas

Calvin Cycle: a series of
reactions that produces a
6-carbon sugar.
● The Calvin
Cycle occurs in
the Stroma
●CO2 is the carbon ● The Calvin Cycle used to be
source for the sugars referred to as the dark reactions.
DO NOT be confused. The
reactions can take place with or
without light.
1.
2.
_________ is the source of carbon to make
sugar.
The Calvin Cycle occurs in the ________ of
the chloroplast.
•
Reactants: CO2, Energy Transporters (ATP &
NADPH)
•
The energy in ATP & NADPH is transferred into
the CO2 during the Calvin cycle rearranging bonds
to form G3P
•
Product: G3P
• G3P: a three carbon sugar that goes onto to be turned into some
other macromolecule (glucose, starch, etc)
The ATP used in the Calvin Cycle came from the
________ reaction.
