8.3 Photosynthesis Flashcards
cluster of chlorophyll and proteins found in thylakoids
photosystem
series of electron carrier proteins that shuttle high-energy electrons during ATP-generating reactions
electron transport chain
What does ATP synthase do?
Create ATP in chemiosmosis
The major products of the light-dependent reactions are
ATP and NADH
What is the function of NADPH and ATP in the Calvin cycle?
They provide the energy required to build high-energy sugars
What is used to reduce NADP in the light dependent reactions of photosynthesis?
Electrons from photosystem I
Which space has the highest H+ concentration in a chloroplast?
Thylakoid space
Which process occurs during the light dependent reaction of photosynthesis?
ATP and O2 are produced
Where does photoactivation of electrons take place
Photosystems I and II
What is produced by the photolysis of two water molecules?
O2 + 4H+ + 4e-
How does chlorophyll a in Photosystem II replace its electrons?
From the photolysis of water
What kind of organism is used in Calvin’s lollipop experiment?
Algae
What element’s radioactive version in Calvin’s experiment
Carbon
Organic compounds produced throughout Calvin cycle are separated during the experiment with what technique
Chromatography
Any radioactive carbon compounds on the chromatogram were then identified using
Autoradiography
How many carbon atoms are in RuBP?
5
What provides the reducing power for the Calvin cycle?
NADPH2
Main products of the Calvin Cycle
ADP, NADP+, Glucose
The Calvin Cycle occurs in the
Stroma
5 carbon sugar that combines with CO2 in the Calvin Cycle
RuBP
Where does the CO2 used in the Calvin Cycle originate from
Diffusion through the stoma
True or False: The Calvin Cycle returns ADP and NADP to the light dependent phase
True
The enzyme responsible for Carbon Fixation in C3 Photosynthesis is
Rubisco
where does light reaction take place
thylakoid membrane
