Fatty acids move through the plasma membrane by which transport method?
Correct answer: A. Passive transport
- A. Passive transport
- B. Non-facilitated transport
- C. Active transport
- D. Facilitated transport
Explanation
Fatty acids move across the plasma membrane primarily through passive transport. This is possible because fatty acids are hydrophobic and can dissolve in the lipids of the phospholipid bilayer, allowing them to passively diffuse down their concentration gradient without energy input. Other transport methods like active transport are energy-dependent and not typically used by hydrophobic molecules like fatty acids. Facilitated transport, while also a passive process, often involves transport proteins and is more applicable to polar or larger molecules rather than simple hydrophobic ones.
