What is the goal of bioremediation? - To clean up areas polluted with toxic compounds using bacteria Broad-spectrum antibiotics inhibit the growth of most intestinal bacteria. Consequently, assuming that nothing is done to counter the reduction of intestinal bacteria, a hospital patient who is receiving broadspectrum antibiotics is most likely to become - deficient in certain vitamins and nutrients If prokaryotes did not exist, what would change in the nitrogen cycle? - The rate of movement ...

Oxygenic photosynthesis -found in cyanobacteria -uses H2O as proton donor -Produces O2 -2 photosystems -linear flow of electrons -uses Calvin cycle -uses Chl a Anoxygenic photosynthesis -uses H2S as proton donor -produces S -green sulphur bacteria use reverse cycle to incorporate CO2 rather than produce it -green non-sulphur bacteria use the hydroxypropionate pathway (ancestral pathway) Photosystem I -similar to Chlorobi (Green S. bacteria) and Firmicutes (Heliobacterium) -has ferrodoxin Phot...
