◉ When proteins are used as a source of energy fr the body, the
proteins. a. are converted into glucose molecules, which are fed into
glycolysis.
b. are converted mainly into intermediates of glycolysis or the citric
acid cycle.
c. are hydrolyzed to their constituent amino acids; electrons are
stripped from the amino acids and passed to the electron transport
chain.
d. are hydrolyzed to glucose and converted to acetyl CoA, which
enters the citric acid cycle. Answer: Are converted mainly into
intermediates of glycolysis or the citric acid cycle
◉ A culture of bacteria growing aerobically is fed glucose containing
radioactive carbon and is then examined. During the citric acid cycle,
radioactivity would first appear in .Answer: Citrate
◉ Humans use the calories they obtain from _____ as their source of
energy . Answer: Food
,◉ The conversion of CO2 and H@O into organic compounds using
energy from light is called .Answer: Photosynthesis
◉ During cellular respiration, NADH . Answer: Delivers its electron
load to the first electron carrier molecule
◉ Which of the following statements regarding the chemical
grooming of pyruvate is false .Answer: Each pyruvate molecule has a
CO2 added and then joins with an NADH
◉ As a scientist employed by the FDA, you've been asked to sit on a
panel to evaluate a pharmaceutical company's application for
approval of a new weight loss drug called Fat Away. The company
has submitted a report summarizing the results of their animal and
human testing. In the report, it was noted that Fat Away works by
affecting the electron transport chain. It decreases the synthesis of
ATP by making the mitochondrial membrane permeable to H+,
which allows H+ to leak from the intermembrane space to the
mitochondrial matrix. This effect leads to weight loss.
Fat Away prevents ATP from being made by .Answer: Destroying the
H+ gradient that allows ATP synthase to work
,◉ After glycolysis but before the citric acid cycle .Answer: Pyruvate
is oxidized
◉ The mitochondrial cristae are an adaptation that a. permits the
expansion of mitochondria as oxygen accumulates in the
mitochondrial matrix.
b. helps mitochondria divide during times of greatest cellular
respiration.
c. increases the space for more copies of the electron transport chain
and ATP synthase complexes.
d. carefully encloses the DNA housed within the mitochondrial
matrix. Answer: Increases the space for more copies of the electron
transport chain and ATP synthase complexes
◉ Which of the following colors contributes the least energy to
photosynthesis? Answer: Green
◉ Carbon fixation Answer: Occurs when carbon atoms from CO2 are
incorporated into an organic molecule
◉ Ozone Answer: Protects Earth from UV radiation
◉ Photoautotrophs Answer: Produces organic molecules from
inorganic molecule
, ◉ To produce one glucose, the Calvin cycle needs to be run through
_____ times Answer: Six
◉ What is the source of energy that provides the boost for electrons
during photosynthesis Answer: Light
◉ The energy that excites P680and P700 is supplied by Answer:
Photons
◉ A redox reaction involves the transfer of Answer: An electron
◉ Which of the following are produced during the Calvin cycle
Answer: Glucose, ADP, NADP+
◉ Of the following wavelengths of light, which would you expect to
be reflected or transmitted by chlorophyll a Answer: Green
◉ Which of the following is an example of a photoautotroph
Answer: Cyanobacteria in freshwater and marine ecosystems
◉ Which of the following statements concerning the role of redox
reactions in photosynthesis and cellular respiration is true a.
