Analyze the physiological roles of the listed options

• Cholesterol: Primarily used for cell membrane structure and steroid hormone synthesis.
• Vitamins: Act mainly as organic coenzymes, but do not directly serve as structural components like phosphate in ATP/nucleic acids.
• Lipids: Serve as energy storage, structural components of cell membranes, and signaling molecules.
• Minerals: Inorganic elements including calcium (essential for blood clotting), phosphorus (essential for ATP, DNA, and RNA backbones), and magnesium/zinc (essential cofactors for enzyme function).

Match functions to the correct nutrient class

• Enzyme function: Requires mineral cofactors (e.g., \(Mg^{2+}\), \(Zn^{2+}\)).
• ATP production: Requires phosphorus (phosphate groups).
• DNA and RNA synthesis: Requires phosphorus for the sugar-phosphate backbone.
• Blood clotting: Requires calcium (\(Ca^{2+}\)).
• Therefore, minerals are the essential nutrients for all these specified functions.
