10-1 Introduction
10-2 Microbes must first find and transport the elements that they need
10-3 Carbon can be assimilated from organic source or synthesized from CO₂
10-4 Nitrogen assimilation can involve the uptake of reduced nitrogen compounds or nitrogen fixation
10-5 Sulfur can come from organic or inorganic sources
10-6 Phosphate enters metabolism by ATP synthesis and substrate-level phosphorylation.
10-7 Metal ions, important components of many enzymes, must be taken up from the environment
10-8 The environment influences the ability of a microbe to make monomers
10-9 Amino acids that are simple in structure have simple biosynthetic pathways
10-10 The synthesis of some amino acids share common steps
10-11 Amino acids with more complex structures have longer biosynthesis pathways
10-12 Nucleotide synthesis is complex and expensive
10-13 Lipid synthesis involves a carrier protein
10-14 Monomers are assembled to form polymers
10-15 Peptidoglycan begins in the cytoplasm and ends in the periplasm
10-16 Synthesized polymers combine in orderly fashion to make cellular stuctures.
