The large number of ATPs produced are:

Options

A. inside the mitochondria matrix and diffuse out through the membrane
B. inside the mitochondria matrix and leave through a channel protein
C. outside the mitochondria and diffuse in through the membrane
D. outside the mitochondria and enter through a channel protein

Explanation

To answer the question regarding where the large number of ATPs are produced in the process of respiration in plants, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding ATP Production**:
- ATP (Adenosine Triphosphate) is the primary energy currency of the cell. It is produced during cellular respiration, which occurs in different stages.

2. **Identifying the Stages of Cellular Respiration**:
- Cellular respiration consists of three main stages: Glycolysis, the Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain (ETC).

3. **Glycolysis**:
- Glycolysis occurs in the cytoplasm and produces a small amount of ATP. Specifically, it generates **2 ATP molecules** per glucose molecule.

4. **Krebs Cycle**:
- The Krebs Cycle takes place in the mitochondrial matrix. This cycle also produces a limited amount of ATP, specifically **2 ATP molecules** per glucose molecule.

5. **Electron Transport Chain (ETC)**:
- The ETC occurs in the inner mitochondrial membrane. This stage is where the majority of ATP is produced, generating approximately **34 ATP molecules** per glucose molecule.

6. **Total ATP Production**:
- When we sum up the ATP produced from all stages:
- Glycolysis: 2 ATP
- Krebs Cycle: 2 ATP
- Electron Transport Chain: 34 ATP
- Total: **2 + 2 + 34 = 38 ATP** (though the net yield is often considered as 36 ATP due to the energy cost of transporting some intermediates).

7. **Conclusion**:
- The large number of ATPs (34 ATPs) are produced in the **Electron Transport Chain** within the mitochondria.

### Final Answer:
The large number of ATPs produced are primarily in the **Electron Transport Chain** located in the **mitochondrial membrane**.
