Which statement best describes how an electron transport chain captures energy
present in electron donors such as NADH and FADH2? - Answer water flowing down a
series of rapids
As a result of electron transport, a proton gradient is formed, and ATP is synthesized
by a process known as ______ phosphorylation. - Answer oxidative
Which two of these molecules serve to connect complexes I-IV of the eukaryotic ETC
with each other? - Answer Coenzyme Q and Cytochrome C
Choose the two mechanisms that likely transport protons across the membrane in
the ETC. - Answer Protons can be actively pumped across the membrane
Protons can be translocates when carrier that accept both electrons and protons
transfer electrons to carriers that only accept electrons
Select all of these statements that correctly describe differences between the
electron transport chains of prokaryotic and eukaryotic cells. - Answer - Prokaryotic
ETCs may have more entry and exit points for electrons.
, - Prokaryotic ETCs may be branched.
- Prokaryotic ETCs may be shorter
Select the two sources of energy available to organisms. - Answer light
certain chemical compounds
Select the two sources of electrons available to all organisms. - Answer - Reduced
inorganic compounds
- Reduced organic compunds
Select the two sources of carbon available to all organisms. - Answer CO2
reduced organic compounds
Choose two roles of chemolithoautotrophs in ecosystems. - Answer They recycle
elements from the reduced inorganic compounds they use as source of energy
and electrons.
They are primary producers.
Although sources of energy, electrons, and carbon are diverse, all are used to generate
which three main products? - Answer reducing power, precursor metabolites, ATP
In general terms, the two sources of energy available for organisms are certain
chemicals (e.g., carbohydrates, proteins, and fats) and _______. - Answer light
Which metabolic pathway does not require oxygen and does not use a proton
motive force to generate ATP energy? - Answer fermentation
