i-rock-roll said:Can anyone help me describe the steps of the enzyme synthesis diagram. Please describe each step 1, 2 ,3 http://www.bbc.co.uk/scotland/learning/bitesize/standard/biology/investigating_cells/enzymes_and_aerobic_respiration_rev4.shtml
The first step in enzyme synthesis is transcription, where the DNA sequence for the enzyme is transcribed into mRNA.
The mRNA then travels out of the nucleus and into the cytoplasm, where it attaches to a ribosome for translation.
tRNA molecules bring amino acids to the ribosome, where they are assembled in the correct sequence according to the mRNA code.
The newly synthesized enzyme is guided into its correct shape by chaperone proteins, which help prevent misfolding and ensure proper function.
The final step is post-translational modification, where the enzyme may undergo additional changes such as the addition of a cofactor or cleavage of certain peptide bonds to become fully functional.
