Which of the following is true about substrate level phosphorylation?
It involves ATP synthase
It involves the transfer of phosphate groups by dehydrogenase enzymes
It only occurs in the presence of oxygen
It requires energy released from facilitated diffusion of protons down their electrochemical gradient
It is used to make ATP during the Calvin cycle
A microbe lives solely on acetate. It has an Electron Transport Chain driven by oxygen that has two hydrogen pumps and both NADH and FADH deliver their hydrogens (and electrons) to the first pump hence each generates 2 ATP. How many ATP are generated per acetate molecule?
We know that atmospheric oxygen (O2) can be a final electron acceptor at the end of the electron transport chain in aerobic respiration.
Name 2 other inorganic molecules that can be final electron acceptors at the end of the electron transport chain in anaerobic respiration.
Name 1 organic molecule that can be a final electron acceptor in fermentation.

One group of such microorganisms are lithotrophs. These are found deep beneath the Earth's surface, living on rocks under anaerobic conditions and surviving on CO2 as their sole source of carbon. Imagine that you are studying a newly discovered lithotroph and are trying to determine what it uses as a source of electrons for reducing CO2 and for producing energy. Which one of the following conditions must be met for a molecule to serve as a useful electron donor? Oxidation of the molecule occurs with a decrease in free energy.
