The rather low catalytic activity ... WebJan 3, 2024 · 1. Making Aminoacyl-tRNAs. Translation is perhaps the most energy-intensive job a cell must do, beginning with the attachment of amino acids to their tRNAs. The basic amino-acylation reaction is the same for all amino acids. A specific aminoacyl-tRNA synthase attaches each tRNA to ( charges) an appropriate amino acid.
