Question

Cyanobacteria are a large group of prokaryotic organisms. Cyanobacteria are found in marine microbial mats that include many species of eukaryotic and prokaryotic organisms that can participate in mutualistic symbiotic relationships. One recently discovered species of cyanobacteria, UCYN-A, lacks the genes that encode ribulose bisphosphate carboxylase/oxygenase (RuBisCo), components of photosystem II, and the Krebs cycle. UCYN-A contains genes enabling nitrogen fixation, which allows the enzymatic conversion of atmospheric nitrogen to biologically available nitrogen compounds such as nitrate. Within the microbial community there is relatively little available nitrogen. The majority of organisms in the microbial mat cannot fix nitrogen.

Identify the metabolic process whereby UCYN-A is most likely to produce ATIP.

Answer 1

Answer: The metabolic process win which UCYN-A is most likely to produce ATP is called Metabolic streamlining.

Step-by-step explanation:

cyano bacterium (UCYN-A) is widespread in the oceans and important in the marine cycle. It uses light energy, carbon dioxide and water which happens in the thylakoid that helps generate ATP.

UCYN-A helps in nitrogen fixation in the surface waters of the ocean which is very important for the symbiosis the metabolic process to produces ATP.

Metabolic streamlining: in an open-ocean nitrogen-fixing cyanobacterium. It was found that UCYN-A lacks a number of major metabolic pathways including the tricarboxylic acid cycle, but retains sufficient electron transport capacity to reducing power from light and to generate energy.
