Other examples are the synthesis of large proteins from amino acid building blocks, and the synthesis of new DNA strands from nucleic acid building blocks. Catabolic reactions release energy, some of which is conserved in the synthesis of ATP and release electron carriers (NADH, NADPH, and FADH 2), the rest of lost as heat. In stage II of catabolism, the metabolic pathway known as glycolysis converts glucose into two molecules of pyruvate (a three-carbon compound with three carbon atoms) with the corresponding production of adenosine triphosphate (ATP). Building block molecules for biosynthetic pathways come from the cell's catabolic pathways and from the environment.
