1.
Which of the following best describes the main
purpose of the combined processes of glycolysis
incorrect? (Concept 9.3
) [Hint]
The citric acid cycle oxidizes the
products of glycolysis to carbon dioxide.
and cellular respiration? (Concept 9.1
) [Hint]
the breakdown of glucose to carbon
dioxide and water
The citric acid cycle produces most of
the NADH that is subsequently used by
the electron transport chain.
conserving the energy in glucose and
related molecules in a chemical form
that cells can use for work
The oxidation of compounds by the
citric acid cycle requires molecular
oxygen.
catabolism of sugars and related
compounds
The last reaction in the citric acid cycle
produces a product that is a substrate
for the first reaction of the citric acid
cycle.
producing complex molecules from
chemical building blocks
The citric acid cycle depends on the
availability of NAD+, which is a product
of the electron transport chain.
breaking down ATP, so that ADP and P
can be reused
2.
In the combined processes of glycolysis and
cellular respiration, what is consumed and what
9.
is produced? (Concept 9.1
) [Hint]
Carbon dioxide is consumed, and water
is produced.
Oxygen participates directly in the
reaction that makes ATP from ADP and
P.
Water is consumed, and ATP is
produced.
The chemiosmotic synthesis of ATP
requires that the electron transport in
the inner mitochondrial membrane be
coupled to proton transport across the
same membrane.
Glucose is consumed, and carbon
dioxide is produced.
ATP is consumed, and oxygen is
produced.
The first two choices are correct.
Which of the following describes the process of
glycolysis? (Concept 9.2
) [Hint]
It represents the first steps in the
chemical oxidation of glucose by the
cell.
It produces both ATP and NADH.
It converts one glucose molecule to two
molecules of pyruvate and carbon
dioxide.
The first two answers are correct.
Which of the following statements is correct
about the chemiosmotic synthesis of ATP?
(Concept 9.4
) [Hint]
The energy for production of ATP from
ADP comes directly from a gradient of
electrons across the inner mitochondrial
membrane.
Oxygen is consumed, and glucose is
produced.
3.
Which statement about the citric acid cycle is
The first three choices are correct.
10
.
In most cells, not all of the carbon that enters
glycolysis is converted to carbon dioxide by
cellular respiration. What happens to this carbon
that does not end up as CO2? (Concept 9.6
[Hint]
It is used to convert ADP to ATP via
chemiosmosis.
It is converted to heat.
The first three answers are correct.
5.
The electrons stripped from glucose in cellular
respiration end up in which compound? (Concept
9.4
) [Hint]
ATP
NADH
oxygen
carbon dioxide
water
The carbon atoms are removed from
these processes to serve as building
blocks for other complex molecules.
It is used to make ATP.
It is used to make NADH.
