In which process is energy used to build complex molecules from simpler molecules?
a)glycolysis
b)anabolism
c)catabolism
d)respiration

I believe the correct answer is B. The process of anabolism involves the synthesis of complex molecules from the simpler ones. It  is one of the metabolic pathways together with catabolism. Anabolism is a process wherein a body uses energy released from the process of catabolism in order to form complex molecules. There are three stages of this process. First, the production of the precursor molecules like nucleotides, monosaccharides and amino acids. Second, the activation of the precursor molecules using energy from ATP. Lastly, the formation of the precursor molecules into the complex  molecules like polysaccharides, nucleic acids, proteins and lipids.
