Photosynthesis
Basics
Basics
What process do plants use to make their own food?
Photosynthesis
Where do light-dependent reactions happen?
Thylakoid membranes
How many main photosystems are involved?
Two
Where does the Calvin Cycle happen?
Stroma
What does the light-dependent reaction provide for the Calvin Cycle?
ATP and NADPH
Where does photosynthesis mainly occur?
Chloroplasts
What molecule is split during the light reactions?
Water
What are they called?
Photosystem I and Photosystem II
What gas enters the Calvin Cycle?
CO₂
What does CO₂ provide to the Calvin Cycle?
Carbon
What type of energy does photosynthesis use?
Light energy
What two energy-carrying molecules are produced?
ATP and NADPH
Which photosystem splits water?
Photosystem II
What enzyme attaches CO₂ to RuBP?
RuBisCO
What does ATP provide?
Energy
What sugar is produced during photosynthesis?
Glucose
What ions flow through ATP synthase?
H⁺ ions
Which photosystem helps produce NADPH?
Photosystem I
What molecule is produced by the Calvin Cycle?
G3P
What does NADPH provide?
High-energy electrons
What gas is released as a byproduct?
Oxygen
What does ATP synthase produce?
ATP
What pigment absorbs light energy?
Chlorophyll
What are the three stages of the Calvin Cycle?
Carbon fixation, reduction, and regeneration
In one sentence, how do the two stages work together?
The light reactions produce ATP and NADPH, and the Calvin Cycle uses them with CO₂ to produce G3P.
