Electron acceptors in ETS are arranged according to

Options

A. Decreasing positive potential
B. Increasing positive potential
C. Increasing negative potential
D. None of the above

Answer

### Step-by-Step Solution:

1. **Understanding ETS**: The Electron Transport System (ETS) is a series of complexes and other molecules that transfer electrons from electron donors to electron acceptors via redox reactions. This process is crucial for cellular respiration and energy production.

2. **Role of Electrons**: Electrons are negatively charged particles. In the context of the ETS, they move from a lower potential energy state to a higher potential energy state. This movement is essential for the generation of ATP.

3. **Proton Movement**: Protons (H⁺ ions), which are positively charged, move in the opposite direction. They flow from a higher potential energy state to a lower potential energy state. This movement is also crucial for creating a proton gradient used in ATP synthesis.

4. **Arrangement of Electron Acceptors**: The electron acceptors (or carriers) in the ETS are arranged according to their electrochemical potential. Specifically, they are organized in order of increasing positive potential. This arrangement facilitates the efficient transfer of electrons through the system.

5. **Conclusion**: Therefore, the electron acceptors in the Electron Transport System are arranged according to increasing positive potential. This arrangement allows for the smooth flow of electrons from one carrier to the next, ultimately leading to ATP production.

### Final Answer:
The electron acceptors in the Electron Transport System (ETS) are arranged according to increasing positive potential.
