1a.ATP (F1F0) synthase
   uses substrate level phosphorylation to make ATP
   uses proton motive force (PMF) to make ATP
   can run in forward (ATP synthesis) and reverse (ATP hydrolysis)
   both (B) AND (C)

1b.In the absence of oxygen, prokaryotic respiration
   can function only in autotrophs that assimilate CO2
   cannot function
   can function with alternate electron acceptors such as nitrate (N03)
   (a) AND (c)

is oxidized
   is reduced
   is catabolized

Solution

1a. Runs in the opposite direction, creating ATP while using the proton motive force created by the electron transport chain as a source of energy.

uses proton motive force (PMF) to make ATP.

1b. Anaerobic respiration is a type of respiration. Fermentation includes processes that use an organic molecule.

can function with alternate electron acceptors such as nitrate (N03).
