Some notable examples include: - Protein Synthesis: Ribosomes catalyze the formation of peptide bonds. - DNA Replication: DNA polymerase catalyzes the addition of nucleotide triphosphates to a growing DNA strand. - Lipid Synthesis: Acetyl-CoA carboxylase catalyzes the carboxylation of acetyl-CoA to malonyl-CoA, a key step in fatty acid synthesis.
