Question

if a person does not follow good dental hygiene practices, the debris becomes food for bacteria that live on teeth. as the bacteria metabolize ____, they produce ____ that damages tooth enamel and results in decay.
multiple choice
fructose, amylase
alcohol, dehydrogenase
carbohydrate, amylase
carbohydrate, acid

Explanation:

Bacteria on teeth metabolize carbohydrates present in food debris. During this metabolism, they produce acids which erode tooth enamel leading to decay. Amylase is an enzyme, not a product of bacterial metabolism causing decay. Dehydrogenase is an enzyme related to other metabolic processes not directly linked to tooth - decay in this context.

Answer:

D. carbohydrate, acid
