Name the high-energy electron carrier in photosynthesis.
NADP+
100
What are all three names for the second half of Photosynthesis?
Dark Reactions, Calvin Cycle, Light Independent Reactions
100
What is the plant organelle where light is absorbed?
Chloroplast
100
What is the final product of the Calvin Cycle?
One G3P
200
What is the equation for Photosynthesis?
6CO2 + 6H20 ->light-> C6H12O6 + CO2
200
What is the name of the movement of H+ current through an enzyme? (Using a concentration gradient for power)
Photophosphorylation
200
How many G3P make 1 glucose?
2
200
What is the name of the membrane where the light-dependent reactions of photosynthesis occur?
Thylakoid membrane
200
What are the final products of the light dependent reactions of Photosynthesis?
O2, NADPH and ATP.
300
What green tissue are the chloroplasts concentrated in?
The mesophyll
300
What is photolysis of H2O and what are it's three products?
Splitting of water using light: Replaces the electrons in Photosystem II, H+ ion for concentration gradient, and O2 as waste.
300
Where do the ADP and NADP+ go after they have been used?
Light Independent Reactions
300
Where is the high hydrogen ion that powers the hydrogen pump?
Lumen/Thylakoid space.
300
What is produced from the photolysis of water in Photosystem 2?
Oxygen
400
What three colors do chlorophylls absorb?
Red, Violet, and Blue
400
What is the energy from the excited electrons used for in the Electron Transport Chain?
Moving H+ ions through the thylacoid membrane to create a concentration gradient.
400
Daily Double: How is 3-PGA made?
RuBP and CO2 catalyzed by Rubisco.
400
Where does the Calvin Cycle occur?
Stroma
400
What is the high-energy electron acceptor that is REDUCED after Photosystem 1?
NADPH
500
Why do leaves turn colors in the fall?
The chlorophylls break down, causing red/orange/yellow light to be reflected, since nothing is there that can absorb it. The carotenoids remain, that reflect red/orange/yellow light.
500
What does it mean to be oxidized and reduced? Give an example of each in the light reactions.
Oxidized- lose electron(s) Reduced- gain electron(s)
Chlorophyll A/PSI/PSII - Oxidized
Primary Electron Accepter - Reduced
500
How many ATP and how many NADPH are used to make 1 Glucose?
18 ATP and 12 NADPH
500
In what step does carbon fixation occur in Photosynthesis?
