question 42
cheese, yogurt, and buttermilk are produced by bacteria that form ____.
○ a. citrate
○ b. lactic acid
○ c. pyruvate
○ d. ethyl alcohol
○ e. acetaldehyde

Explanation:

Cheese, yogurt, and buttermilk are products of lactic acid fermentation. In lactic acid fermentation, bacteria (such as Lactobacillus) convert sugars (like lactose in milk) into lactic acid. This process gives these dairy products their characteristic texture and flavor. Citrate is not the key product in their formation. Pyruvate is an intermediate in cellular respiration (not the end - product for these fermented foods). Ethyl alcohol is a product of alcoholic fermentation (e.g., in yeast for beer and wine production). Acetaldehyde is also not the relevant product here.

Answer:

B. lactic acid
