Explanation

The text explicitly states: 'To mark a protein for destruction, the cell commonly attaches molecules of a small protein called ubiquitin to the protein. Giant protein complexes called proteasomes then recognize the ubiquitin tagged proteins and degrade them.' This describes the ubiquitin-proteasome system as a post-translational control mechanism for protein degradation.
