Which process builds up food molecules into more complex molecules?

Question

Quizplus · Accepted Answer

Anabolism is a process in which the body builds up complex molecules from simpler ones, such as building muscle tissue from amino acids obtained from protein in food. This process requires energy and is the opposite of catabolism, which breaks down complex molecules into simpler ones. Nutrition and absorption are important processes for obtaining nutrients from food, but they do not specifically involve building up complex molecules.
