Enzyme A works optimally at pH 7, however, it was removed from its environment and placed into a pH of 1. This is not in its working range. This enzyme is not nonfunctioning how it used too. What do we call the process of an enzyme becoming not functional due to pH change or temp change?

• Naturing

• Denaturing

• Transcription

• Translation

Enzyme A works optimally at pH 7, however, it was removed from its environment and placed into a pH of 1. This is not in its working range. This enzyme is not functioning how it used too. Why is the enzyme not functional anymore?

• The enzyme shape has altered

• The enzyme changed color

• The enzyme used all the substrate

• The substrate change shape

One morning, Drake ate lots of salt and vinegar chips, which have lots of acid on them. Throughout the day, Drake was feeling stomach pains and his food in his stomach is not being broken down by the enzymes. Why would the enzymes in Drakes stomach not break down the food?

• The enzymes have denatured due to the acid in the chips changing the shape of the enzyme.

• The enzymes in the stomach have broken the substrate down in to smaller parts

• The enzymes in the stomach have built the pieces of substrate in to larger molecules called polymers

• The enzymes will function normally not matter the pH change.

What occured to the enzyme in the beef liver, catalase?

• it was denatured due to being heated

• it was denatured due to being in acidic conditions

• it was catalyzed due to the basic conditions

• it was denatured due to the non optimal pH conditions
