Question

7. In Part G, it is likely that a heavy precipitate formed in one or more test tubes. It is likely that the precipitate was

a. denatured enzyme.

b. digested enzyme.

c. inhibitor combined with cofactor.

d. More than one answer is correct.

Explain your answer:

Answer 1

denatured enzyme.

It will eventually melt over time and turn into water. Is there a way to make it melt faster? Yes- put it in a pot and turn on the stove. Chemical reactions involve substrates (your ice cube) and products (the water). Enzymes help turn substrates into products faster than if left to form over time; they increase the rate of reaction, or catalyze the reaction. In this case, the stove enzyme helped you turn the ice cube into water faster than if you just let it sit in the pot to melt naturally. Notice the stove is unchanged- it's still a stove that will cook whatever you want. Enzymes are also unchanged when they catalyze reactions.
