Cyanobacteria are a large group of prokaryotic organisms which generally appear blue-green in color. One recently discovered species of cyanobacteria, UCYN-A, lacks the genes that encode:
Components of photosystem II in the light reactions of photosynthesis.
Ribulose bisphosphate carboxylase/oxygenase (RuBisCo) in the Calvin Cycle of photosynthesis.
Components of the Calvin Cycle in respiration.
However, UCYN-A contains genes that enable nitrogen fixation, allowing the conversion of nitrogen into a more complex compound, such as nitrate, NO3¯.
Use the information above to answer the following questions.
What color(s) of light is the cyanobacteria likely to absorb?
A researcher investigating UCYN-A suggests that, like other cyanobacteria, it undergoes photosynthesis. Do you agree or disagree with the researcher's statement? Explain your reasoning.
Identify the metabolic process whereby UCYN-A is most likely to produce ATP.
Discuss how nitrogen fixation could be a similar process to carbon fixation.
