Overview of Metabolism & the Provision of Metabolic Fuels

LEARNING OBJECTIVES
After studying this lesson, students should be able to:

  • Explain what is meant by anabolic, catabolic, and amphibolic metabolic pathways.
  • Describe in outline the metabolism of carbohydrates, lipids, and amino acids at the level of tissues and organs, and at the subcellular level, and the interconversion of metabolic fuels.
  • Describe the ways in which flux of metabolites through metabolic pathways is regulated.
  • Describe how a supply of metabolic fuels is provided in the fed and fasting states; the formation of metabolic fuels reserves in the fed state and their mobilization in fasting.
