How are cell membranes selectively permeable?
Understand the Problem
The question is asking about the mechanisms that enable cell membranes to allow certain substances to pass through while blocking others. This involves concepts related to membrane structure and function, transport proteins, and the properties of the lipid bilayer.
Answer
The cell membrane is selectively permeable due to its phospholipid bilayer and proteins.
The final answer is the cell membrane is selectively permeable due to its phospholipid bilayer and proteins that control the entry and exit of specific substances.
Answer for screen readers
The final answer is the cell membrane is selectively permeable due to its phospholipid bilayer and proteins that control the entry and exit of specific substances.
More Information
The phospholipid bilayer and membrane proteins are critical in creating selective permeability, allowing cells to maintain homeostasis.
Tips
Common mistakes include not recognizing the dual role of the bilayer and proteins in selective permeability.
