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 temperature will Pepsin, in the graph, be the least functional?

• 40 degrees Celsius

• 30 degrees Celsius

• 60 degrees Celsius

• 90 degrees Celsius

Kristina is studying enzymes and noticed that the protein. The protein in question is shown and has a specific shape. Kristina is manipulating this protein by dropping the temperature to out of the protein's working range. What would be Kristina's observation be after dropping the temperature of the Hemoglobin protein to freezing (out of optimal range) be? SELECT ALL THAT APPLY

• The protein denatured and changed shape

• The protein denatured and does not function the same

• The protein's polypeptide sequence is getting longer

• Translation occurs before transcription

Why are there many codon options for the amino acid Proline (Pro)?

• this allows for less changes in the polypeptide sequence, resulting the same protein and less mutations if the polymerase was to and a mistake

• this allows for more changes in the polypeptide sequence, resulting the same protein and less mutations if the polymerase was to and a mistake

• So that the mRNA can fit in the ribosome and be read three RNA bases at a time

• So that there are not different triglyceride produced

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.

What does lactase do to lactose?

• break down the bigger sugar, lactose, into monosaccharides

• break down the bigger sugar, lactose, into lipids

• Combine the monosaccharides to form the bigger sugar, lactose

• Combine the nucleic acids to form the bigger sugar, lactose
