Enzyme Quiz

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

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.

If the person that ate the dairy/lactose was to have a fever of 104.3 degrees fahrenheit. What would occur to the protein if this is out of the optimal range of operation? SELECT ALL THAT APPLY

• 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

Where do instructions to synthesize glucocerebrosidase originate from?

• DNA

• mRNA

• tRNA

• Amino Acids

An enzyme called glucocerebrosidase breaks down a glycolipid in the body known as glucocerebroside. However, in a genetic disease known as Gaucher’s disease, the body does not produce enough glucocerebrosidase. Therefore glucocerebroside can build up in the body and this can cause serious side effects such as anemia and swelling of the liver and spleen.

What is the substrate in the scenario?

• a glycolipid

• a protein

• the enzyme

• spleen

ATP is produced by cellular respiration in your human body cells. There are a variety of enzymes that work to produce ATP, but one of those enzymes is called phosphofructokinase-1. This enzyme is sensitive to blood acidity. Blood can become more acidic if a patient is in respiratory distress. If you were under respiratory distress, what would be occurring to the phosphofructokinase-1?

• It will change shape and function less if at all.

• It will NOT change shape, but it WILL change function

• It will change shape, but it will NOT change function

• it will NOT change shape, and NOT change function

Which two enzymes share a working pH of 7.5?

• Pepsin and Salivary Amylase

• Alkaline Phosphatase and Pepsin

• Pepsin only works at a pH of 6

• Salivary Amylase and Alkaline Phosphatase
