Energy transuding membrane in chloroplast is

Options

A. Outer unit membrane
B. Inner unit membrane
C. Thylakoid membrane
D. Cristae

Answer

To answer the question "Energy transducing membrane in chloroplast is," we can follow these steps:

### Step 1: Understand the Structure of Chloroplasts
Chloroplasts are organelles found in plant cells that are responsible for photosynthesis. They have a complex internal structure, including an outer membrane, inner membrane, and thylakoids.

### Step 2: Identify the Membranes
- **Outer Membrane**: This is the outermost layer of the chloroplast.
- **Inner Membrane**: This lies just inside the outer membrane and surrounds the stroma.
- **Thylakoid Membrane**: These are the membranes that form the thylakoids, which are stacked in structures called grana.

### Step 3: Determine the Function of Each Membrane
The thylakoid membrane is where the light-dependent reactions of photosynthesis occur. It contains the protein complexes necessary for the electron transport chain, which is crucial for ATP production.

### Step 4: Identify the Energy Transducing Membrane
The term "energy transducing membrane" refers to a membrane that is involved in converting energy from one form to another, specifically in the context of ATP synthesis. In chloroplasts, this function is primarily carried out by the thylakoid membrane.

### Step 5: Conclusion
Based on the functions of the membranes in chloroplasts, the energy transducing membrane is the **thylakoid membrane**.

### Final Answer
The energy transducing membrane in chloroplasts is the **thylakoid membrane**.
