Describe how NADH and FADH2 are converted into ATP by
the electron transport chain and ATP synthase. Describe the
proteins involved, and describe the roles of H+,
e-, and O2 in the process.
Assuming the electron transport chain received electrons from
NADH and FADH2 in a 3:1 ratio as the wild type for a
particular organism, what would the consequences be of a change to
a 1:1 ratio? Select all that apply.
1. NADH and FADH2 deliver their high energy electrons
to
A. glycolysis
b. the electron transport chain
c. oxygen
2. In fermentation, which set of pathways is running, or
operating?
A. glycolysis
b. transition
c. Kreb's cycle (also called TCA cycle or citric acid cycle)
d. electron transport chain
e. all of the above
3. As electrons are passed down the electron transport
chain, the energy is used to pump ______ across the
membrane.
A. B.H+, or hydrogen ions
b....
Explain how the electron transport chain functions to generate
ATP in terms of electron
carriers, oxygen as the electron acceptor, the four inner membrane
proteins, the hydrogen
concentration gradient, water and ATP synthase.
How does uncoupling the electron transport chain from ATP
synthesis cause thermogenesis? Describe how the two processes and
how they are coupled. Describe one way that they can become
uncoupled.
Electron Transport Chain (McKee
364-372).
Describe the initial substrates of the electron
transport chain based on the cofactors that supply one pair of
electrons
Describe the final product based on the acceptor of one
pair of electrons from the electron transport chain
Describe the locations of ubiquinone (UQ) and
cytochrome C (Cyt C) in relation to the electron transport
chain
Describe the source of electrons for the reaction
between oxidized UQ and reduced UQ (UQH2) based on the
redox reaction...
1. Compare and contrast the point of entry for NADH-derived
electrons into the electron-transport chain on the matrix side vs
the cytosolic side of the inner mitochondrial membrane. Which of
these entry points provides the most energy? Why?
