Fill in the following blanks with suitable words:
Anaerobic respiration by yeast converts glucose into ………… which is used in making wine or beer.

Options

A. Lactic acid
B. Alcohol
C. Glycogen
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Anaerobic Respiration**: Anaerobic respiration is a type of respiration that occurs in the absence of oxygen. It is a process that allows organisms to produce energy without using oxygen.

2. **Identifying the Organism**: In this case, the organism involved in anaerobic respiration is yeast. Yeast is a unicellular fungus that plays a crucial role in fermentation processes.

3. **The Process of Anaerobic Respiration in Yeast**: During anaerobic respiration, yeast breaks down glucose. The breakdown of glucose in the absence of oxygen leads to the production of two main products: alcohol and carbon dioxide.

4. **Filling in the Blank**: The specific type of alcohol produced during this process is ethanol. Ethanol is the compound that is used in the production of alcoholic beverages such as wine and beer.

5. **Final Answer**: Therefore, the complete statement is: "Anaerobic respiration by yeast converts glucose into **ethanol** which is used in making wine or beer."
