Which of the following answer choices includes the proper terms to metabolically describe the process of digesting lactose? correct answer: It is a catabolic process with an exergonic reaction that results in an output of energy. Why do you, as a living organism, need to continually consume food? correct answer: Food is broken down by catabolic pathways and converted to ATP, which is then used to fuel anabolic pathways.
