- action of pepsin on photographic film. The photographic film is made up of three layers, plastic, photographic pigment and gelatine in between. See diagram: The protease enzyme digests the gelatine section, causing the other two layers to fall apart. Pepsin is a digestive enzyme found in the gastric juice of the stomach.

Pepsin And Enzyme Activity - Pepsin Enzyme

- Pepsin is a digestive enzyme produced in the stomach. It breaks down protein into smaller molecules. The enzymes in your stomach, in turn, help digest the food you eat. Pepsin is also responsible for breaking down the food you eat into smaller molecules. That’s why it’s hard to digest hard-to-digest foods, such as tough meats or tough ...

- Preliminary experiment: We are investigating the best pH at which Trypsin works. Method: A beaker was filled with water of about 400C. Each test tube was filled with 5cm3 of trypsin and 5cm3 of water with a buffer solution one pH 4 one pH 7 and the other pH 9. A piece of 1cm2 photographic film was dropped in. At this time the stop clock was started.

Pepsin - Wikipedia
- https://en.wikipedia.org/wiki/Pepsin
- Pepsin / ˈ p ɛ p s ɪ n / is an endopeptidase that breaks down proteins into smaller peptides.It is produced in the gastric chief cells of the stomach lining and is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food.Pepsin is an aspartic protease, using a catalytic aspartate in its active site.

- Background: As you know from reviewing the Pepsin Report, pepsin is an enzyme that hydrolyzes the peptide bond of a substrate. As a result, the protein is cleaved into smaller units. The reaction (as is most enzyme reactions) is pH dependent. It is the purpose of this experiment to investigate the pH dependence of the pepsin reaction.

- 1. Active pepsin-albumin fibers may be prepared by spreading monolayers from mixed solutions at pH 4, and compressing the film into a fiber. 2. 2. Enzyme activity of the compressed films may be measured by microscopic observation of self-digestion in acid solution and by microdetermination of trichloroacetic acid-soluble products of proteolysis.
Photographic film - Wikipedia
- https://en.wikipedia.org/wiki/Photographic_film
- Photographic film is a strip or sheet of transparent film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast, and resolution of the film.. The emulsion will gradually darken if left exposed to light, but the process is too slow and ...

- Class practical or demonstration. Exposed and developed black and white negative film is black because it contains light-sensitive silver halides (salts). Black and white film is composed of a plastic backing covered with a mixture of gelatine ( protein) and silver halides. Digestion of the gelatine (protein) by trypsin releases the silver salts and the film clears.
