Biology Coursework The reaction Between Gelatine and Trypsin
I am going to investigate how photographic film can be recycled to be reused again.
The photographic film has a silver compound on it which needs to be separated from
the plastic. If the silver compound was to come off then the plastic would go clear. If
we were to use an industrial process it would be too expensive, so our task is to make
it cost efficient. Exposed photographic film contains black grains of silver compound.
The particles of silver are attached to the film by an insoluble compound called
gelatine. To achieve this goal I have been asked to find the optimum temperature at
which this process is most efficient. I will use an enzyme called Trypsin to dissolve
the gelatine in the photographic film. However gelatine is in soluble in water if the
water is not at a high temperature. When the enzyme digests the gelatine it forms
soluble amino acids. These acids dissolve and take the silver compounds with them.
