Fluid mosaic model of plasma membrane states that protein molecules float in a fluid _ layer.
Correct answer: B. Phospholipids
- A. Galactose
- B. Phospholipids
- C. Glucose
- D. Carbohydrate
Explanation
Phospholipids: This option is the correct answer. The fluid mosaic model of the plasma membrane states that protein molecules float in a fluid phospholipid layer. Phospholipids are the main components of the plasma membrane, forming a bilayer structure. The hydrophilic (water-loving) phosphate heads of the phospholipids face outward, interacting with the watery environment, while the hydrophobic (water-fearing) fatty acid tails face inward, creating a barrier.
