Question

The table below compares two types of respiration.


Respiration Types
Type A Type B
Carbon dioxide produced Yes No
Fermentation involved No Yes


Which statement about Type A and Type B respiration is correct?
Type A respiration involves electron transport, but Type B respiration does not.
Type A respiration produces lactic acid, but Type B respiration does not.
Type A respiration does not involve glycolysis, but Type B respiration involves glycolysis.
Type A respiration produces ATP, but Type B respiration does not produce ATP.

Answer 1

To analyze the statements, we need to understand the characteristics of each type of respiration based on the table.

- **Type A respiration**: Produces carbon dioxide, does not involve fermentation.
- **Type B respiration**: Does not produce carbon dioxide, involves fermentation.

Now, let's examine each statement:

1. **Type A respiration involves electron transport, but Type B respiration does not.**
- Correct. Type A respiration typically refers to aerobic respiration, which involves the electron transport chain. Type B (fermentation) does not involve electron transport.

2. **Type A respiration produces lactic acid, but Type B respiration does not.**
- Incorrect. Lactic acid is produced through certain fermentation pathways, which is what Type B respiration involves.

3. **Type A respiration does not involve glycolysis, but Type B respiration involves glycolysis.**
- Incorrect. Glycolysis occurs in both Type A respiration and Type B respiration.

4. **Type A respiration produces ATP, but Type B respiration does not produce ATP.**
- Incorrect. Both types of respiration produce ATP, though the mechanisms and amounts differ.

Based on this analysis, the correct statement is:
**Type A respiration involves electron transport, but Type B respiration does not.**
