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
