The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Concepts**: - Simple diffusion and facilitated diffusion are both processes that allow substances to move across a cell membrane. - Simple diffusion occurs directly through the lipid bilayer, while facilitated diffusion requires specific transport proteins. 2. **Identifying the Nature of Transport**: - Both simple and facilitated diffusion are types of passive transport, meaning they do not require energy (ATP) to occur. They rely on the concentration gradient, moving substances from an area of higher concentration to an area of lower concentration. 3. **Analyzing the Options**: - **Option A**: "Do not require ATP energy." - This is correct for both types of diffusion. - **Option B**: "Show uphill transport requires spatial membrane proteins." - This is incorrect because both types of diffusion move substances down their concentration gradient, not uphill. - **Option C**: "Cannot transfer substances having a hydrophobic moiety." - This is also incorrect. Facilitated diffusion can help transport hydrophobic substances if the right transport proteins are present. 4. **Conclusion**: - The correct statement regarding both simple and facilitated diffusion is that they "do not require ATP energy." ### Final Answer: - The correct option is **A: Do not require ATP energy.** ---
