How is synthesis defined in biological terms?

In biological terms, synthesis refers to the process where simple substances are combined to create more complex compounds. This is fundamental to various biological processes, such as the formation of proteins from amino acids, the creation of nucleic acids from nucleotides, and the synthesis of lipids from fatty acids and glycerol. By understanding synthesis as a means of building complex molecules essential for life, we can appreciate its role in growth, cellular repair, and the overall functioning of living organisms. The specific actions of enzymes and metabolic pathways enable cells to carry out these synthetic processes efficiently, highlighting the importance of synthesis in maintaining life.
