How do the reaction kinetics of ribozymes compare to those of protein enzymes?
What will be an ideal response?
Ans: The results of the analysis of Michaelis-Menten kinetics indicate that the ribozymes are highly specific for their substrates (as indicated by the low KM values) and that they are generally slower than protein enzymes (as indicated by the lower rates of turnover).
