Photosynthesis - Chapter 8 - College Biology Flashcards
1
Q
light reaction (4)
A
1) Chlorophyll absorbs light energy, exciting electrons.
2) Water molecules are split to release oxygen, protons, and electrons.
3) Excited electrons travel through the ETC, creating a proton gradient.
4) The proton gradient drives ATP synthesis, and electrons reduce NADP+ to NADPH.
2
Q
where does light reaction take place?
A
Thylakoid of chloroplasts
3
Q
Inputs (4) and outputs (3) of light reaction
A
In - H20, light energy, NADP+, ADP+Pi
Out - NADPH, ATP, O
4
Q
Calvin cycle (3)
A
1) Co2 combines with RuBP, forming 3PGA
2) 3 PGA converts to G3P using ATP and NADPH
3) G3P used to regenerate RuBP, allowing cycle to restart
5
Q
Inputs (3) and outputs of Calvin Cycle (3)
A
In - CO2, ATP, NADH
Out - G3P, ADP, NADP+
6
Q
Where does Calvin cycle occur?
A
Stoma of Chloroplasts
