Why do extreme haloph es need such high A to stablize ribosomes C to counteract high K E. A and B B. to stabilize D as an electron acceptor 28 Whrdo extreme halophies need such A. to stabize ribosomes c to counteract high lNa I E. A and c B to stablue cell wals o as an electron acceptor e microorganisms in the above que a. Archaea B.Barteria c Eukarya D they can be any of these 30. Bacteriorhodopsinisin the membrane as part of an ETS B, membrane but mo part of an ETS periplas 31, Batteriorhodopsin can convert light to ATP by A substrate level phosphorylation c reverse electron transport ive phosphorylation D. none of these some bacteria get rid of mertu A they reduce B they convert very toxic form to less toxic form Cther comert to a volatile formthat moves away metabolize it in both the near amvironment and the cytoplasm E at of he above Min mata disease was named fter a terrible ew A. in apan knowinely put took mercury into Minimata Bay a company pan put slightly to mercury into Minimata Bay ethylated mercury when got to th e sediment in the Ba D bacteria demethylated which went bark into the dc together occurred E. both B

Solution

27. B. to stabilize cell walls.

sodium ions maintain the osmolarity of the cells and keep the cell walls intact. when they are transferred to normal water, they immediately lyse due to less osmolarity.

28. B. to stabilize the cell walls.

29. D. any of these.

In general, they belong to archae bacteria, but there are some archaebacteria even in eukaryota.

30. A

bacteriorhodosin is in the membrane of ETS

31. C. oxidative phosphorylation.

32. D. all of the above.

some bacteria reduce it to elemental mercury. some are able resist it. some convert it to volatie form.

33. B.

Chisso company in Minimata started releasing its waste into sea water without knowledge of presence of mercury. the side reactions in the factory produced methylmercury, a toxic form.
