Lab 8– Enzymes In this experiment we studied enzymes which are proteins that speed up chemical reactions. We  specifically used two enzymes: amylase and bromelain and conducted two experiments. We first  studied how amylase – an enzyme found in saliva - breaks down starch. Amylase breaks down  the hydrolysis of starch to the point of where it turns to maltose. Iodine is orange, but when added to starch it is purple. However when you add amylase to the starch and iodine, it returns to orange because the amylase breaks down the starch. We did two experiments: 1. We tested  - Whatever the salivary amylase doesn’t break down the pancreatic amylase breaks down

Unformatted text preview: -The more saliva added the quicker the breakdown -Enzymes are large proteins that bind substrates at their active sites. Which is the substrate in this experiment? – starch What is the enzyme doing? – the enzyme is splitting the substrate Amylase Results – didn’t get expected results. It was supposed to turn yellow----Bromelain – eznyme extracted from fresh pineapples-Bromelain breaks down polypeptide chains, which normally bind jello (powder and hot water) and make it jello-Heat stops bromelain from breaking down the polypeptide chain. Pineapple/Bromelain Results Fresh – liquid Heated – solid Canned – solid Water – solidifed...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
