Question

22. Enzymes are biological catalysts that speed-up the biochemical reactions in living cells without being changed themselves. (a) In terms of overcoming the transition state of a biochemical reaction, explain how enzyme aids to speed-up biochemical reactions. (4%) (b) Use a simple labelled diagram to illustrate the below statement: "The specificity of enzymatic reactions can be explained by the Lock-and-Key-Model". (5%)
