23S rRNA catalyze peptide-bond formation explained by the model of proton shuttle given in figure.

 Which of the following statements is/are CORRECT for this model?

A. Base pairing between the 23S rRNA and the CCA ends of the tRNAs in the A- and P-sites positions is crucial for this reaction

B. This catalytic mechanism involves entropy

C. 2’-OH of the P-site tRNA act as part of a “proton shuttle”

D. it is a protein that catalyses peptide bond formation
