What is the primary role of sterols in cell membranes?
Understand the Problem
The question is asking about the main function of sterols within cell membranes and provides multiple-choice answers to choose from.
Answer
Sterols maintain membrane fluidity in cell membranes.
The primary role of sterols in cell membranes is to maintain membrane fluidity.
Answer for screen readers
The primary role of sterols in cell membranes is to maintain membrane fluidity.
More Information
Sterols, including cholesterol in animal cells, are critical for maintaining the appropriate fluidity of cell membranes, crucial for fluidity and also serve roles in signaling pathways. They support the structural integrity and functionality of the cell membrane, contributing to membrane stability and permeability.
Tips
A common mistake is to overlook the dual function of sterols - while their primary role is maintaining fluidity, they also contribute to membrane stability and signaling.
