- Nitrosomonas is a photophobic (light-avoiding) chemoautotrophic bacterium that converts ammonia into nitrite. Explain how the organism can fix CO2 via the Calvin cycle in the absence of sunlight.The common name for species like Anabena is blue-green algae. This group of bacteria are capable of photosynthesizing. Do they contain chloroplasts? Explain.Ubiquinone and cytochrome c are both electron carriers that are easily diffused. Say whether it is true or false, if it is wrong to justify it

EscherichiaYou have discovered a cyanobacterium with only photosystem I (it has no photosystem II).This bacterium is unable to fix CO2. Explain thoroughly how you think this microorganismmakes ATP and reducing power?Compare photo litho autotrophy with chemo-organo heterotrophy. Sun light is the ultimate source of energy and all living organisms obtain their energy directly or indirectly from the sun. However in deep-sea vents (where there is no sun light) life has originated and the many groups of microorganisms are flourishing in such environment. How? Explain your reasoning
- If algae are exposed to 14CO2 for a brief period while illuminated, the labeled carbon is initially found almost entirely in the carboxyl group of 3-phosphoglycerate. However, if illumination is continued after the label pulse, other carbon atoms become labeled. Explain.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?Contrast autotrophy in the following phototrophs:cyanobacteria; purple and green sulfur bacteria; Chloroflexus.
