Metabolism: The Use of Energy in Biosynthesis

Chapter Objectives

After reading this chapter you should be able to:

discuss the use of energy to construct more complex molecules and structures from smaller, simpler precursors
discuss the way that biosynthetic pathways are organized to conserve genetic storage space, biosynthetic raw materials, and energy
discuss the way that autotrophs use ATP and NADPH (or NADH) to reduce carbon dioxide and incorporate it into organic material
describe the assimilation of phosphorus, sulfur, and nitrogen
discuss the use of the TCA cycle as an amphibolic pathway and the need for anaplerotic reactions to maintain adequate levels of TCA cycle intermediates
discuss the synthesis of glucose (gluconeogenesis) and the synthesis of fatty acids
describe in general terms the synthesis of peptidoglycan and the construction of new cell walls
