What does the chemiosmotic process in chloroplasts involve? - A) establishment of a proton gradient
In glycolysis, for each molecule of glucose oxidized to pyruvate - B) 2 molecules of ATP are used and 4
molecules of ATP are produced.
In chemiosmotic phosphorylation, what is the most direct source of energy that is used to convert ADP +
Pi to ATP? - D) energy released from movement of protons through ATP synthase
Which statement describes the functioning of photosystem II? - D) The electron vacancies in P680 are
filled by electrons derived from water.
The primary role of oxygen in cellular respiration is to - B) act as an acceptor for electrons and hydrogen,
forming water.
During aerobic respiration, which of the following directly donates electrons to the electron transport
chain at the lowest energy level? - E) FADH2
Which of the following is likely to lead to an increase in the concentration of ATP in a cell? - B) an
increase in a cell's catabolic activity
What wavelength of light in the figure is most effective in driving photosynthesis? - A) 420 mm
Figure 10.1 shows the absorption spectrum for chlorophyll a and the action spectrum for
photosynthesis. Why are they different? - D) Other pigments absorb light in addition to chlorophyll a.
The oxygen consumed during cellular respiration is involved directly in which process or event? - B)
accepting electrons at the end of the electron transport chain
, In a plant cell, where are the ATP synthase complexes located? - D) A and C....thylakoid membrane &
plasma membrane
Where does the Calvin cycle take place? - A) stroma of the chloroplast
Photorespiration lowers the efficiency of photosynthesis by preventing the formation of - B) 3-
phosphoglycerate molecules
Which metabolic pathway is common to both cellular respiration and fermentation? - D) glycolysis
Why are C4 plants able to photosynthesize with no apparent photorespiration? - B) They use PEP
carboxylase to initially fix CO2 .
What are the products of linear photophosphorylation? - C) ATP and NADPH
The ATP made during glycolysis is generated by - A) substrate-level phosphorylation.
The molecule that functions as the reducing agent (electron donor) in a redox or oxidation-reduction
reaction - B) loses electrons and loses energy.
Which of the following is an example of potential rather than kinetic energy? - D) a food molecule made
up of energy-rich macromolecules
When a molecule of NAD+ (nicotinamide adenine dinucleotide) gains a hydrogen atom (not a hydrogen
ion) the molecule becomes - C) reduced.
What is proton-motive force? - B) the transmembrane proton concentration gradient
CAM plants keep stomata closed in daytime, thus reducing loss of water. They can do this because they -
fix CO2 into organic acids during the night.
