Chapter 8: Energy from Nutrients
Now that you’ve learned about the three energy-yielding macronutrients, it’s time to focus on that “energy-yielding” function of these molecules. In this chapter, there will be a brief introduction to energy in living systems, followed by an overview of the chemical reactions that occur within cells that take the energy stored in carbohydrates, lipids, and proteins, and convert that energy to a form that your cells can use to do the work of life.
