|
Gibbs Free Energy |
the amount of energy within a molecule that could perform useful work at a constant temperature. (measured in kj/mole) |
|
|
|
What are thebenefits of coupled reactions? |
Pairan energetically unfavourable reaction with one that is energeticallyfavourable and hence has an overall negative Gibbs free energy to allow thereaction to take place |
|
|
|
Where islysozyme found and how does it provide defence against bacteria? |
Tears and nasal secretions. Hydrolyses the bond between the repeatingdisaccharide NAG (N-acetylglucosamine) and NAM (N-acetyl muramic acid) in thebacterial cell wall making it lyse. |
|
|
|
How do enzymes work? |
Enzymes arrange substrates in such a way that the bonds are strained. |
|
|
|
Define transition state |
Enzymes arrange substrates in such a way that the bonds are strained. |

|
· Describe themechanism of action of lysozyme. |
Glu-35 protonates the oxygen in theglycosidic bond thus breaking it. Asp-52 stabilises the positively chargedintermediate that’s formed. · Water becomes de protonated by Glu-35 whichreturns the Glu-35 to its original state. · The hydroxide ion then attacks thepositively charged intermediate adding an OH to it. |
