ANSWERS!!
The energy released by the transfer of electrons through the Electron Transport Chain is used
to generate a proton gradient in mitochondria by pumping H+ ions into which of the
following cellular locations?
a) nucleoplasm
b) space between inner and outer mitochondrial membranes
c) cytosol
d) from the cytosol into the mitoplasm
e) none of these is correct correct answers b) space between inner and outer mitochondrial
membranes
In addition to ATP, what are the end products of glycolysis?
a) H2O, FADH2, and citrate
b) CO2 and NADH
c) NADH and pyruvate
d) CO2 and pyruvate
e) none of these is correct correct answers c) NADH and pyruvate
ADP (adenosine diphosphate) itself is a structural part of which of the following coenzymes
that are used in cellular respiration?
a) NAD+
b) FADH2
c) CoASH
d) ATP
e) ADP is part of all of these coenzymes correct answers e) ADP is part of all of these
coenzymes
Which cellular respiration metabolic pathway is common to both the processes of
fermentation and cellular respiration?
a) citric acid cycle
b) electron transport chain
c) glycolysis
d) conversion of pyruvate to sucrose
e) none of these is correct correct answers c) glycolysis
Photosynthetic CO2 is reduced to carbohydrate in which of the following plant processes
a) the C4-Hatch & Slack pathway
b) the Calvin cycle
c) the light reactions of photosynthesis
d) a and b are correct
e) a, b, and c are correct correct answers d) a and b are correct
, The process where an electron leaves a chlorophyll molecule leaving that chlorophyll charged
is
a) photobleaching
b) photoionization
c) photorespiration
d) resonance
e) none of these is correct correct answers b) photoionization
The dark reactions of photosynthesis require?
a) ATP
b) NADPH
c) CO2
d) RuBP carboxylase (Rubisco)
e) all of these are needed correct answers e) all of these are needed
Measurements of the amount of DNA per nucleus were taken on a large number of cells from
a growing fungus. The measured DNA levels ranged from 5 to 10 picograms per nucleus. It is
most likely that a cell which contained 5 picograms of DNA was in the following stage of the
cell cycle
a) G1
b) G2
c) M
d) none of these is correct correct answers a) G1
One way photosynthesis in a typical C4 plant differs from that in a C3 plant, is that the C4
plants
a) C4 does not produce any oxygen gas at all
b) C4 actively pumps oxygen gas away from the cells that contain rubisco
c) C4 avoids the use of rubisco entirely; instead, it uses only PEP carboxylase to catalyze
carbon fixation
d) C4 keeps its stomata more open, so that more CO2 can enter the plant
e) C4 carries out the Calvin cycle only in the chloroplasts of its bundle-sheath cells correct
answers e) C4 carries out the Calvin cycle only in the chloroplasts of its bundle-sheath cells

a) functioning mitochondria
b) oxygen
c) oxidative phosphorylation of ATP
d) NAD+
