Milk is converted to yogurt under certain conditions when the microorganisms in the milk produce acid. Which of these processes would you expect to be key in the production of yogurt?
a. Photosynthesis
b. Lactic acid fermentation
c. Krebs cycle
d. Alcoholic fermentation
Answer:
b. Lactic acid fermentation
Explanation:
Lactic acid fermentation occurs when pyruvate formed by glycolysis is reduced into lactate under the anaerobic conditions. The NADH serves as an electron donor for the reduction of pyruvate into lactic acid. Lactic acid bacteria are the anaerobic bacteria that ferment the milk sugar lactose into lactic acid. This converts the milk into yogurt. <em>Lactobacillus, Streptococcus salivarius</em>, etc. are mostly responsible for the conversion of milk into yogurt.
