C. Light-harvesting complexes
D. Primary electron acceptor
E. All of the above Correct Answers E. All of the above
Both mitochondria and chloroplasts __________. Correct
Answers Use chemiosmosis to produce ATP
Carbon dioxide and oxygen enter and exit a leaf by diffusion.
Which structure(s) on a leaf allow(s) this process to happen?
Correct Answers Stomata
Chlorophyll molecules are in which part of the chloroplast?
Correct Answers Thylakoid membranes
During the Calvin cycle, what happens during the carbon
fixation phase? Correct Answers The Calvin cycle incorporates
each CO2 molecule, one at a time, by attaching it to a five-
carbon sugar named ribulose bisphosphate.
During which process is molecular oxygen produced in
photosynthesis? Correct Answers The light reactions by linear
electron flow
G3P is used in which of the following processes?
, A. Production of glucose
B. Production of cellulose
C. Production of sucrose
D. Production of starch
E. Production of cell walls in growing plants
F. All of the above Correct Answers F. All of the above
How does carbon dioxide enter the leaf? Correct Answers
Through the stomata
In photosynthesis, plants use carbon from __________ to make
sugar and other organic molecules. Correct Answers Carbon
dioxide
In the light reactions of photosynthesis, ATP is produced by
photophosphorylation. Which process is most similar to
photophosphorylation? Correct Answers Oxidative
phosphorylation in cellular respiration
Metabolic pathways are typically redox processes. In
photosynthesis, what molecule is oxidized and what molecule is
reduced? Correct Answers Water is oxidized and carbon
dioxide is reduced.
Of the following, which occurs during the Calvin cycle?
A. Co2 is reduced
B. Photons are absorbed
