follow the directions.

1. label the process that shows alcoholic fermentation.
2. label the process that shows lactic acid fermentation.

glycolysis
circle the correct answer. questions may have more than one correct answer.

1. alcoholic fermentation is used to make which product?

bread cheese yogurt pickles

1. what kind of taste do lactic acid bacteria give foods?

sweet salty sour spicy

1. what are some milk products made from lactic acid fermentation?

milk sour cream yogurt cheese

1. what is one main difference between fermentation and aerobic respiration?

Explanation:

• For question 3: As per the text, alcoholic fermentation is used in bread (as it makes bread rise) and alcoholic beverages. So bread is correct.
• For question 4: Lactic acid fermentation gives a sour taste (e.g., yogurt which is sour).
• For question 5: Sour cream and yogurt are milk - products made from lactic acid fermentation.
• For question 6: Fermentation is respiration without oxygen (anaerobic), while aerobic respiration requires oxygen.

Answer:

1. bread
2. sour
3. sour cream, yogurt
4. Fermentation is anaerobic (no oxygen needed), aerobic respiration requires oxygen.
