Which of the following types of protein degradation is mediated by the ubiquitin-proteasome system?

A Proteolysis by lysosomal enzymes
B Proteolysis by calcium-dependent proteases
C Proteolysis by ATP-dependent proteases
D Proteolysis by ubiquitin-proteasome system ✓

Explanation

The ubiquitin-proteasome system is a type of protein degradation that involves the tagging of proteins with ubiquitin molecules, which are then recognized and degraded by the proteasome.
