Lab Report (Enzyme/Protase Lab) (: 9/26/2012 ... Pour each gelatin concentration into a graduated cylinder. It can be found in Accent Meat Tenderizer. After that, I recalculated the percent mass alcohol of... ...Alum Lab Conclusion The name protein catalyst suggests that most enzymes are made of proteins. Two constants in the lab were the amount of pineapple juice added to the jello and the amount of water in the jello. Each type of pineapple will be in its own, labelled petri dish. canned pineapple comes from overseas, largely from the Philippines. Hypothesis: We think that the fresh pineapples and the frozen fresh pineapples will prevent the jelly from becoming set. Why is water used as a “juice” in Enzyme Lab 1? Knowing the effects of different environmental factors on this enzyme is very valuable. Measured Melting Point | 93 (degrees C) | 91.5 (degrees C) | Materials: -Petri dish w/ pre-made strawberry jell-o (3) -Fresh pineapple -Canned pineapple -Spoon Procedure: In this lab, you will test the effect of pineapple (both fresh and canned) on gelatin. But they do not undergo permanent changes and so remain unchanged at the end of the reaction. General: Size 12 font, Times New Roman, 1 inch margins, double spaced. The crude aqueous extract from the pineapple fruit is known as bromelain. Results Activity: Fruit Added to Jell-OObserved Effect on Gelatin (Jell-O) **Record Every 5 minute intervals**Control (no added fruit) Fresh Pineapple Canned Pineapple Conclusion Explain the results of your experiment. Made from bone� made from protein� so it must be tough stuff! After a reaction has been catalyzed, the catalyst can be used again to catalyze the same reaction. Looking at the graph, the speed of the fresh pineapple is 2mL/min. You know enough about enzymes not to figure this out. So why can�t you put fresh pineapple in it? PRE-LAB QUESTIONS: (You may need to refer to your class notes to answer these questions) Chemically speaking, what is gelatin made of (is it a carbohydrate, a protein, or a lipid)? Enzyme Pineapple Lab Introduction: BACKGROUND: • Gelatin is made from a protein called collagenwhich comes from the joints of animals. 6. ...The Effect of Pineapple Juice on the Gelling Time of Gelatin There were six different accelerations for each trial and they are: 7.88 … The enzyme in pineapple that dissolves protein is called bromelain. ��ࡱ� > �� � � ���� � � ���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������� _� �� 2 bjbj 4b b b J( � �� �� �� � � � & & � � � ���� � � � 8 � \ B d � �A t � � � � � � � � EA GA GA GA GA GA GA $ :C � �E l kA � � e @ � � � kA & & � � � �A Q Q Q � � & R � ( � � EA Q � EA Q Q � Q= x " �@ � ���� ��4z߭� ���� w � m> " 1A �A 0 �A �> XF � XF D �@ XF � �@ � � � Q � � � � � kA kA � � � � � �A � � � � ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� XF � � � � � � � � � � � : Pineapple Enzyme Pre-Lab! Conclusion: Write a word �equation� to explain the chemical reaction that took place in one of your petri-dish. Enzymes are very efficient catalysts for biochemical reactions.
