Options

A. `1andoo`
B. `gt1andlt1`
C. `ooand1`
D. 1 and 1

Answer

To solve the question regarding the respiratory quotient (RQ) of maturing fatty seeds and germinating fatty seeds, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Respiratory Quotient (RQ)**:
- RQ is defined as the ratio of the volume of carbon dioxide produced to the volume of oxygen consumed during respiration.
- It helps in determining the type of substrate being used for respiration.

2. **Identify RQ Values for Different Substrates**:
- The RQ values vary depending on the type of substrate:
- Carbohydrates: RQ = 1
- Fats: RQ = 0.7
- Proteins: RQ = 0.8
- Organic acids: RQ > 1

3. **Analyze the Two Stages of Fatty Seeds**:
- **Maturing Fatty Seeds**: At this stage, the seeds contain a mix of fats and carbohydrates. The presence of carbohydrates increases the RQ value, making it greater than 1.
- **Germinating Fatty Seeds**: During germination, the seeds primarily utilize fats for energy, which gives them an RQ value of 0.7.

4. **Conclude the RQ Values**:
- For maturing fatty seeds, the RQ is more than 1 due to the presence of carbohydrates.
- For germinating fatty seeds, the RQ is 0.7 because they predominantly use fats for respiration.

### Final Answer:
- The respiratory quotient of maturing fatty seeds is **more than 1**, and for germinating fatty seeds, it is **0.7**.
