chemical energy.
The light reactions of photosynthesis provide chemical energy in the form of ATP.
-
In the overall equation for photosynthesis, the reactants are
water and carbon dioxide.
-
Which of the following is true regarding the light reactions of photosynthesis?
Green light is not absorbed by the photosynthetic pigments
-
The reaction center of chlorophyll a is an area where solar energy is concentrated.
True
-
During the light reactions, ATP is produced when
hydrogen ions move from the thylakoid space to the stroma.
-
The first step of the Calvin cycle is
the attachment of carbon dioxide to RuBP.
