What happens when enzymes are heated to a very high temperature?
The shapes of the enzyme are changed (or denatured)
Which factors can change the shape of an enzyme and therefore make it not work?
too much heat and changes in pH (acid or base levels)

If enzymes in the stomach prefer to be in a pH of 2 and the enzyme is moved to the intestine with a pH of 8 will the stomach enzymes work in the new place?
yes, enzymes work wherever they are
yes, stomach enzymes work in all parts of the digestive system
no, enzymes only work at their preferred pH
no, not at first but after awhile the enzyme will start to work
This shows an enzyme working on a carbohydrate. Choose the answer that explains what happened.
A is the substrate and the enzyme broke it down for to the body to use
B and C are the molecules the body is eating and the enzyme put it together
A, B and C are all different molecules and the enzyme is working on each one separately
