The incomplete breakdown of sugars in anaerobic respiration results in the formation of

Options

A. Water and carbon dioxide
B. Alcohol and carbon dioxide
C. Fructose and water
D. Glucose and carbon dioxide

Answer

**Step-by-Step Solution:**

1. **Understand Anaerobic Respiration**: Anaerobic respiration occurs in the absence of oxygen. It is a process where glucose is partially broken down to release energy.

2. **Identify the Products of Anaerobic Respiration**: In anaerobic conditions, sugars like glucose do not undergo complete oxidation. Instead, they are converted into simpler compounds.

3. **Know the Common End Products**: The common end products of anaerobic respiration in plants (and some microorganisms) are ethanol (alcohol) and carbon dioxide.

4. **Evaluate the Options**:
- Option 1: Water and carbon dioxide - This is more typical of aerobic respiration.
- Option 2: Alcohol and carbon dioxide - This matches the known products of anaerobic respiration.
- Option 3: Fructose and water - Fructose is a sugar, not a product of respiration.
- Option 4: Glucose and carbon dioxide - Glucose is a reactant, not a product.

5. **Select the Correct Answer**: Based on the understanding of anaerobic respiration and the evaluation of the options, the correct answer is option 2: alcohol and carbon dioxide.

**Final Answer**: The incomplete breakdown of sugars in anaerobic respiration results in the formation of alcohol and carbon dioxide.
