To produce 10 surcr ose mlecules the number of aTP and NADPH + `H^(+)` required in `C_(3)` plants is

Options

A. 360 and 240
B. 300 and 200
C. 180 and 120
D. 320 and 240

Answer

To determine the number of ATP and NADPH + H⁺ required to produce 10 sucrose molecules in C₃ plants, we can follow these steps:

### Step 1: Understand the requirements for one sucrose molecule
In C₃ plants, the Calvin cycle is responsible for the synthesis of sucrose. Each sucrose molecule requires:
- **36 ATP**
- **24 NADPH + H⁺**

### Step 2: Calculate the requirements for 10 sucrose molecules
To find out the total amount of ATP and NADPH + H⁺ needed for 10 sucrose molecules, we multiply the requirements for one sucrose molecule by 10.

1. **ATP Calculation**:
- For 1 sucrose: 36 ATP
- For 10 sucrose: \( 10 \times 36 = 360 \) ATP

2. **NADPH + H⁺ Calculation**:
- For 1 sucrose: 24 NADPH + H⁺
- For 10 sucrose: \( 10 \times 24 = 240 \) NADPH + H⁺

### Step 3: Summarize the results
Thus, to produce 10 sucrose molecules, the total requirements are:
- **360 ATP**
- **240 NADPH + H⁺**

### Final Answer
To produce 10 sucrose molecules in C₃ plants, the number of ATP required is **360** and the number of NADPH + H⁺ required is **240**.
