Which biomolecule is involved in the formation of cell membranes? (2020)
Step 1: Understand what a biomolecule is. Biomolecules are the building blocks of life, including proteins, carbohydrates, lipids, and nucleic acids.
Step 2: Identify the role of cell membranes. Cell membranes protect the cell and control what enters and exits.
Step 3: Learn about lipids. Lipids are a type of biomolecule that includes fats and oils.
Step 4: Focus on phospholipids. Phospholipids are a special kind of lipid that have a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails.
Step 5: Understand how phospholipids form cell membranes. Phospholipids arrange themselves in a double layer (bilayer) with the heads facing outward and the tails facing inward, creating a barrier.
Step 6: Conclude that lipids, especially phospholipids, are crucial for making up cell membranes.
