Transcribed Image Text:**Question:**
Each of the following is a function of membranes *except*:
- defining cell and organelle boundaries.
- information storage.
- regulation of transport.
- cell–cell communication.
- sites for specific biochemical functions.
**Explanation:**
Cell membranes are essential structures that serve several crucial functions within biological systems. They are responsible for defining the boundaries of cells and organelles, ensuring compartmentalization and structural integrity. Membranes regulate the transport of substances in and out of cells and organelles, playing a key role in maintaining homeostasis. They also facilitate cell-cell communication through receptor proteins and signaling pathways and provide sites for specific biochemical functions and reactions to occur.
However, membranes are not involved in information storage, which is primarily the function of nucleic acids within the cell nucleus.
Expert Solution
