Background information and prediction
Pepsin is an enzyme that breaks down protein industrially and also inside the human body. ... This would explain why an enzyme such as pepsin couldn’t break down carbohydrates. ... We will be using albumin as the substance to be decomposed and pepsin and the decomposer. ...
Method
· Set up apparatus as shown in diagram
· Fill the flask with water at the desired temperature
· Ad the test tubes with 5ml of pepsin and 8ml of albumen in to the water baths and put 2 thermometers into the test tubes
· Wait until both test tubes have reached the desired temperature (30°C) by checking the thermometers regularly
· When temperature is right add the pepsin to the albumen quickly and begin timing. ...
· Repeat an additional 2 times for reliability
· Carry out experiment for other desired concentrations. ... The pepsin is an irritant so would have to be handled with care to avoid irritation. ...
Conclusion
Through the results I can see that as the concentration increases so do the rates that the pepsin breaks down the albumen. This is due to the increased number of particles available to break up the proteins in albumin at more areas and at a higher rate.
