Which statement best explains the orientation of the phospholipid molecules in this model?
Understand the Problem
The question is asking for an explanation regarding the orientation of phospholipid molecules in a plasma membrane model of an animal cell. It seeks the best statement that describes how these molecules are arranged in relation to internal and external environments.
Answer
B: The hydrophilic phosphate groups are attracted to the aqueous environments.
The final answer is B: The hydrophilic phosphate groups of the phospholipid molecules are attracted to the aqueous internal and external environments.
Answer for screen readers
The final answer is B: The hydrophilic phosphate groups of the phospholipid molecules are attracted to the aqueous internal and external environments.
More Information
Phospholipids form a bilayer in cell membranes, with hydrophilic 'heads' facing the watery environments inside and outside the cell, while hydrophobic 'tails' face inward, away from water.
Tips
A common mistake is confusing hydrophilic and hydrophobic portions of the phospholipid molecule.
