question
They transform light energy to chemical energy by exciting electrons & then moving them from molecule to molecule (like a chain) on the thylakoid membranes.
answer
What is the function of the photosystems?
question
PSI, PSII, ATP Synthase, & electron transport chain
answer
Label everything in diagram 6.
question
A: Photons enter and go to the chlorophyll; water also enters and goes to the chlorophyll.
A: Electrons in the chlorophyll are excited to a higher energy level & the energy is transferring further into the reaction.
answer
PSII
Q: What is happening with matter?
Q: What is happening with energy?
question
A: The CC transports additional protons (H+) into the lumen.
A: The CC uses the energy in the energy in the electrons, the electrons have lost most of their energy from bringing in the protons (H+).
answer
Cytochrome Complex
Q: What is happening with matter?
Q: What is happening with energy?
question
A: Photons enter the chlorophyll.
A: The electrons in the chlorophyll get excited to a higher energy level again & get used sending the chlorophyll out.
answer
PSI
Q: What is happening with matter?
Q: What is happening with energy?
question
1) Chlorophyll of PSI
2) ATP Synthase
answer
At the end of the electron transport chain, where is the light energy that was absorbed and converted by chlorophyll stored? (2 answers)
question
The potential energy of the proton gradient is used to combine ADP and P to make ATP.
answer
Describe how the proton (H+) gradient is used to make ATP.
question
1) ATP
2) NADPH
answer
What 2 molecules bring chemical energy from the light reactions to the next stage of photosynthesis, the Calvin cycle?
Label diagram 7 with 3 phases of the Calvin cycle.
question
An organic carbon, in the form of CO2, is incorporated into organic molecules.
answer
Phase 1, Description
question
Rubisco
answer
Phase 1, What enzyme catalyzes the reaction in this phase?
question
The organic molecules accept electrons & molecules of G3P are formed.
answer
Phase 2, Description
question
Molecules of G3P & energy from ATP are used to produce molecules of RuBP.
answer
Phase 3, Description
question
B/c it continues on and on, uses the same materials in the same order, repeats itself, & uses some of the left over products.
answer
Why is the series of reactions in the Calvin cycle called a "cycle"?
question
NADPH & ATP
answer
At the end of the Calvin cycle, what molecules have the energy that originally came from light? (2)
question
Sucrose, Starch
answer
Glyceraldehyde-3-phosphate (G3P) can be used by plant cells to make ___ & ___.
question
Sucrose
answer
Which molecule in diagram 11 is used to transport energy to other parts of the plant?
question
Starch
answer
Which molecule in diagram 11 is stored in the plant for later use as an energy source?
question
To convert light energy into chemical energy to feed the plant & keep it alive.
answer
Based on everything you've learned from the animations, what is the overall purpose of photosynthesis?
question
O2 is produced when the plant takes in energy from the sun; water and CO2 form carbohydrates which releases O2 over time.
answer
Describe how oxygen gas (O2) is produced during photosynthesis. Include the specific structures in the plant where the reaction occurs.
question
The electron from a molecule of water goes with H+ to ATP Synthase, which then joins the sugar G3P.
answer
Describe the path of an electron from a molecule of water to the sugar G3P.
question
ATP is formed when an electron travels through PSII to the cytochrome complex then to PSI & then to the ATP synthase.
answer
Describe how ATP is produced in the light reactions.
question
Light energy energizes electrons to make ATP & NADPH, which provide energy to produce G3P in the calvin cycle.
answer
Which of the following statements best explains how the energy in a photon of light is stored in a molecule of the sugar G3P?
question
The remaining five G3P molecules help ATP change into 3ADP and 3P before continuing on with the process to make 3RuBP.
answer
When three molecules of carbon dioxide (Co2) react with three molecules of RuBP during the Calvin cycle, six molecules of the sugar G3P are produced. One G3P molecule exits the Calvin cycle during phase 2. What happens to the other five G3P molecules?
