QUESTION 6 1 points Save Answer Your recent received an annotated genome sequence for a microorganism isolated from the human gut strain BIOS312 which have allowed you to describe that the organism is capable of denitrification. Genes encoding for which enzymes would have been identified in the genome to allow you to describe the microorganisms as a denitrifier? OB nitrate reductase O c nitrite reductase OD nitrite oxidoreductase O E nitrous oxide reductase QUESTION 7Explanation / Answer
5) Answer is A. The product produced by one organism is consumed by other, inorder to make the reaction to proceed to get the end product
6) Answer : B, C and E. The sequential reduction of NO3- to N2 needs four enzymes, namely nitrate reductase (nar), nitrite reductase (nir), nitric oxide reductase (nor) and nitrous oxide reductase (nos).
7) Answer C: chlorophyll. Photosynthetic bacteria also have chlorophylls. Green nonsulfur bacteria have chlorophyll cS. Green sulfur bacteria have chlorophylls c, d, and e. Purple bacteria have bacteriochlorophylls a and b. Heliobacteria have chlorophyll g.
8) Answer B: It is direct phosphorylation of ADP to form ATP that is direct transfer of a phosphoryl (PO3) group to ADP after forming intermediates from the substrate. While oxidative phosphorylation involves transfer of electrons and pumping of protons to form ATP.
10) Answer A: Calvin cycle. Energy spent is higher than energy gained. It uses two types of energy currency namely ATP and NADPH.
