R.Q. of sprouting photo tubers will be

Options

A. a) `gt 1`
B. b) `0`
C. c) `1`
D. d) `lt 1`

Answer

To determine the R.Q. (Respiratory Quotient) of sprouting phototubers, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of R.Q.:**
- R.Q. is defined as the ratio of the volume of carbon dioxide (CO2) produced to the volume of oxygen (O2) consumed during respiration.
- The formula for R.Q. is:
\[ R.Q. = \frac{\text{Volume of CO2 produced}}{\text{Volume of O2 consumed}} \]

2. **Identify the Substrate Used:**
- In the case of sprouting phototubers, the primary substrate for respiration is starch, which is a carbohydrate.

3. **Know the R.Q. Value for Carbohydrates:**
- The R.Q. value for carbohydrates is known to be 1. This means that for every molecule of oxygen consumed, an equal amount of carbon dioxide is produced.

4. **Apply the Information to the Question:**
- Since sprouting phototubers primarily utilize starch (a carbohydrate) for respiration, we can conclude that their R.Q. will also be 1.

5. **Select the Correct Option:**
- Based on our calculations and understanding, the correct option for the R.Q. of sprouting phototubers is:
- **Option C: 1**

### Final Answer:
The R.Q. of sprouting phototubers will be **1**.
