Making Plastic from Protein
Click on the correct answer
1
The word "plastic" means
polymerized
able to be melted
protein
able to be bent
able to be molded
2
The protein in milk is
lactose
butterfat
casein
3
The element found highest in protein which is only rarely found in carbohydrates or fats is
carbon
hydrogen
oxygen
nitrogen
4
The loss of shape of a protein molecule from its natural shape is correctly termed
plasticizing
coagulation
alteration
rubberization
denaturation
5
Another example of denaturation is
stirring milk
heating milk
cooking an egg
making whipped cream from fresh cream
boiling water
6
In this demonstration denaturation occurs by vinegar addition which
dilutes the milk
changes the temperature of the milk
changes the pH of the milk
makes the protein coagulate
7
The plastic Misti made in the demonstration
was able to be stretched
was able to be bent
bounced somewhat
was soft to the touch
had water in it
8
Plastics
are made from milk
have many uses
are used in spacecraft
are found in clothing
are found in automobiles
9
Polymers are
short molecules
extremely long molecules
made of monomers which have been linked together
made of molecules which get tangled together
found in milk
10
Misti's product
was made from plastic
contained polymer molecules
could be used to make thread as can the polymer polyester in clothing
demonstrates the denaturation of a natural polymer
is toxic
