2.3 Medical Uses Of Enzymes Flashcards
CF; repeated lung infections damage lung cells causes them to break up and release DNA
DNA is deposited in lung mucus making it very thick… An enzyme called…
Dornase Alfa, digests DNA in mucus making it easier to cough up
Inhaled directly into the lungs through a jet nebuliser
Alpha-1-Antitrypsin is an enzyme that helps to slow down the breaking up of alveoli due to repeated damage to lung tissue, repeated lung infections causes phagocytes to go to area of infection, these white blood cells release elastase (enzyme) that digests proteins (causes damage to elastic fibres in lungs). Alpha-1-Antitrypsin is a…
Protein that inhibits elastase
Diagnostic enzymes are enzymes that are …
Very specific and can be used to identify very specific diseases
Test strips for urine test for…
Glucose - possible diabetes
Enzymes glucose oxidase and …
Peroxidase are present on the strip
When glucose is present it will combine with glucose oxidase to form…
Gluconic acid and hydrogen peroxide
Chromagen is also present but is normally
Colourless
Peroxidase breaks down the hydrogen peroxide, when this happens, chromagen is…
Oxidised and becomes coloured
More glucose=
More colour change
