7.7 Metabolic Integration

In this chapter, we have focused on the breakdown of glucose. What happens if there is more glucose than is needed by the cell? As well as glucose, you probably consume diverse carbohydrates, lipids, and proteins. How are these broken down? And how are these various metabolic pathways coordinated so that the intracellular level of ATP is maintained in a narrow range? In this final section, we consider how the cell responds to these challenges.
