Question

8a. as are most enzymes, lactase (lactaid) and alpha-galactosidase (beano) are examples of what kind of biological molecule?
a. carbohydrates b. lipids c. proteins d. nucleic acids

8b. lactase and alpha-galactosidase act on what kind of substrates? circle one of the biological molecules on the list above.

Explanation:

Identify the macromolecule class of enzymes

Enzymes, including lactase and alpha-galactosidase, are biological catalysts made of amino acid chains, classifying them as proteins.

Identify the substrates of lactase and alpha-galactosidase

Lactase breaks down lactose, and alpha-galactosidase breaks down complex sugars like raffinose; both of these target substrates are carbohydrates.

Answer:

Question 8A

• a. carbohydrates
• b. lipids
• c. proteins (Correct answer)
• d. nucleic acids
