In this chapter, you will learn about the processes involved in transforming light energy into the potential energy in ATP and NADPH molecules, which are then used as sources of energy for building food molecules (carbohydrates). Before beginning this chapter, you should be able to describe the energetic differences between catabolic and anabolic pathways in metabolism (see Concept 8.1). The following question provides a quick check of your basic knowledge in this area.

Which of the following is a true statement?
Anabolic pathways build molecules, require energy, and are endergonic.
