Verified step by step guidance

Understand the structure and function of the plasma membrane: The plasma membrane is a selectively permeable barrier that surrounds the cell, composed of a phospholipid bilayer with embedded proteins.

Identify the types of transport across the membrane: Transport can be passive (not requiring energy) or active (requiring energy). Carrier proteins are involved in both types but are primarily known for active transport.

Define carrier proteins: Carrier proteins are integral membrane proteins that bind specific molecules and change shape to transport them across the membrane.

Distinguish between passive and active transport: Passive transport involves the movement of molecules down their concentration gradient without energy input, while active transport moves molecules against their concentration gradient, requiring energy, often in the form of ATP.

Recognize the primary role of carrier proteins: Carrier proteins are crucial for active transport, where they facilitate the movement of specific molecules across the membrane, often against their concentration gradient, using energy.
