Most appropriate action of ubiquiting includes: (A) Electron transpo chain, (B) Degradation of proteins, (C) Synthesis of protein, (D) Oxydative deamination
Answer is B. Proteins are marked for degradation by the attachment of ubiquitin to the amino group of the side chain of a lysine residue. Additional ubiquitins are then added to form a multiubiquitin chain. Such polyubiquinatedproteins are recognized and degraded by a large, multisubunit protease complex, called the proteasome
