Question

Quizplus · Accepted Answer

Cholesterol is a lipid molecule that helps regulate the fluidity of animal cell membranes. It acts as a buffer, reducing fluidity at high temperatures and increasing fluidity at low temperatures. Proteins and ATP are not directly involved in regulating membrane fluidity, and magnesium ion has a minimal effect.
