Verified step by step guidance

Understand the concept of the fluid mosaic model: The fluid mosaic model describes the structure of cell membranes, where the membrane is a fluid combination of lipids, proteins, and carbohydrates.

Identify the main components of cell membranes: The primary components are phospholipids, proteins, and cholesterol. Phospholipids form a bilayer, proteins are embedded within this bilayer, and cholesterol is interspersed to provide fluidity and stability.

Evaluate the options given in the problem: Analyze each option to determine which components are part of the fluid mosaic model.

Option analysis: a) Proteins, cholesterol, and triacylglycerols - Triacylglycerols are not a component of the membrane structure. b) Phospholipids, proteins, and cholesterol - All are key components of the membrane. c) Phospholipids, nucleic acids, and cholesterol - Nucleic acids are not part of the membrane structure. d) Eicosanoids, proteins, and phospholipids - Eicosanoids are signaling molecules, not structural components.

Conclude with the correct answer: Based on the analysis, the correct components of the fluid mosaic model are phospholipids, proteins, and cholesterol, which corresponds to option b.
