Directions: Read each statement below carefully.
Place a T on the line if you think a statement it
TRUE. Place an F on the line if you think the
statement is FALSE.
1. Electron transport system makes NADH and
FADH2, high energy molecules which are used to
make ATP in the electron transfer chain.
2. The main function of the electron transfer
chain is the synthesis of 38 molecules of ATP from
the controlled oxidation of the six molecules of
NADH and four molecules of FADH2.
3. In Chemiosmosis, the flow of hydrogens
catalyzes the pairing of a phosphate with ATP,
forming ADP.
4. NAD+ must be reoxidized to NADH for reuse
as an electron carrier for the glycolytic pathway
to continue.
_5. All of the carbohydrate intermediates of
glycolysis are used by other enzymatic reactions
to synthesize fatty acids, the major constituents
of lipids, important energy storage molecules.
6. For each glucose molecule that is broken
down by glycolysis, there is a net gain of iwo
molecules of ATP.
7. For each molecule of glucose which
initially enters glycolysis, the citric acid cycle
makes two molecules of ATP.
_8. Chemiosmosis involves the pumping of
protons through special channels in the
membranes of mitochondria from the inner to
the outer compartment. The pumping establishes
a proton (H) gradient.
9. Fermentation is a process that use an
organic molecule to regenerate NAD* from
NADH
10. Electron Transport and Chemiosmosis have
the same starting materials and end products.
