Abacteria isolated from Yellowstone National Park is found to use the chemical methane as a food source. Which term best describes the
energy source for this organism?
OChemotroph
OPhototroph
OHeterotroph
OAutotroph
While bacteria can meet their nutrient needs and survive on acetic acid as a sole carbon source, human beings cannot. Provide a plausible explanation for this limitation in human beings.
Extremophiles are microorganisms that can survive and proliferate in extreme environments. 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.
Oxidation of the molecule occurs with an increase in free energy.
Reduction of the molecule occurs with a decrease in free energy.
O Reduction of the molecule occurs with an increase in free energy.
