Verified step by step guidance

Understand the structure of the cell membrane: The cell membrane is primarily composed of a phospholipid bilayer, with embedded proteins, cholesterol, and carbohydrates.

Identify the role of phospholipids: Phospholipids form the basic structure of the cell membrane, providing a semi-permeable barrier that separates the cell's interior from the external environment.

Consider the function of cholesterol: Cholesterol is interspersed within the phospholipid bilayer, providing stability and fluidity to the membrane but not directly involved in transport.

Examine the role of glycolipids: Glycolipids are involved in cell recognition and communication, not in active transport.

Focus on integral proteins: Integral proteins span the membrane and are crucial for active transport, as they can move substances against their concentration gradient using energy, typically in the form of ATP.
