ASM Objective: 03.01 Bacteria and Archaea exhibit extensive, and often unique, metabolic diversity (e.g., nitrogen fixation
, methane production, anoxygenic photosynthesis).
1
ASM Objective: 03.02 The interactions of microorganisms among themselves and with their environment are determined b
y their metabolic abilities (e.g., quorum sensing, oxygen consumption, nitrogen transformations).
49
ASM Objective: 03.03 The survival and growth of any microorganism in a given environment depends on its metabolic cha
racteristics.
12
ASM Objective: 03.04 The growth of microorganisms can be controlled by physical, chemical, mechanical, or biological m
eans.
2
ASM Objective: 04.02 Although the central dogma is universal in all cells, the processes of replication, transcription, and tr
anslation differ in Bacteria, Archaea, and Eukaryotes.
