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?

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.

40 degrees Celsius
30 degrees Celsius
60 degrees Celsius
90 degrees Celsius
Lactase is an enzyme that breaks down a sugar found in dairy products known as lactose. Some people are lactose intolerant, and this can be due to not having enough lactase production. People who are lactose intolerant may not feel well after eating foods containing lactose.

the enzyme, lactase, will denature
the enzyme, lactase, will change structure
the enzyme, lactase, will function less - if at all
the enzyme will break more lactose down
the enzyme will break apart into amino acids
