What is the role of proteins in the cell membrane?
Understand the Problem
The text appears to be discussing the functions of proteins in a cell membrane, specifically mentioning their role in maintaining cell shape and acting as enzymes. It takes an example of microvilli on epithelial cells in the gut that contain digestive enzymes.
Answer
Membrane proteins facilitate communication, shape maintenance, response to messengers, transport, and environmental interaction.
Membrane proteins help cells communicate, maintain their shape, respond to chemical messengers, transport materials, and interact with their environment.
Answer for screen readers
Membrane proteins help cells communicate, maintain their shape, respond to chemical messengers, transport materials, and interact with their environment.
More Information
Proteins in the cell membrane assist in maintaining cell integrity and function. They act as receptors, channels, and enzymes, and participate in cell adhesion and migration.
Tips
Confusing the role of proteins with other membrane components like lipids is common. Remember, lipids form the basic structure, while proteins add functional dynamics.
