AP BIO EXAM SEMESTER 2
what are the products of the light reactions that are subsequently used by the calvin cycle
ATP and NADPH
Synthesis of ATP by the chemiosmotic mechanism occurs during
both respiration and photosynthesis
CAM plants keep the stomata closed in daytime, thus reducing the loss of water. They can do this because they
fix carbon dioxide into organic sugars during the night.
requires glucose
neither the light reaction nor the calvin cycle
How is photosynthesis similar in C4 and CAM plants
in both cases, rubisco is not used to fix carbon initially
which of the following does not occur in the calvin cycle
release of oxygen
When oxygen is released as a result of photosynthesis, it is a byproduct of which of the following
splitting of water molecules
Where does the Calvin cycle take place?
stroma of the chloroplast
Requires ATP
the calvin cycle alone
which of the following statements best represents the relationships between the light reactions and the calvin cycle.
the light reaction provides ATP and NADPH to the Calvin Cycle, and the cycle returns ADP, PI, and NADP+ to the light reactions
In mitochondria, chemiosmosis translocates protons from the matrix to the intermembrane space, whereas in chloroplasts, chemiosmosis translocates protons from
the stroma to the thylakoid space
where are the molecules of the electron transport chain found in plants.
thylakoid membranes of the chloroplast
