How Do Cell Membranes Adjust to Temperature Changes?

💡 The Answer

• Cells alter the saturation of fatty acids to maintain optimal membrane fluidity.
• Cholesterol serves as a fluidity buffer, preventing extreme rigidity or flexibility.
• In cold conditions, more unsaturated phospholipids are synthesized to keep membranes flexible.
• Some organisms can remodel their membranes within minutes through enzymatic changes.
• This homeoviscous adaptation is vital for proper protein function and cell signaling.
