The highlighted orange circles are the act ive site which contains aspartate residues which are responsible for breaking the peptide b ond using the process known a s hydrolysis. This picture below shows the amino acid.
a) Suggest how the aspartic acid is responsible for breaking t he peptide bond in the protein.
b) Draw and the label the ene rgy profile diagram for this react ion.
c) Suggest how the enzyme a ction can affect ∆G and ∆S and ex plain why is it so.
8) Bioluminescence is a common characteristics found in many living organisms for different function. One of it is the use of the protein luciferin and the enzyme luciferase as an aid in the production of light.
A simplified formula of the bioluminescent reaction:
ATP(energy) + Luciferin + Luciferase + O2(oxidizer) -> light (photons)
a) Suggest how this reaction can result in the formation of light for the living organisms. b) One of the bioluminescence is the sea firefly that produces the blue light
