In terms of structure, how do channel proteins differ from carrier proteins?

Verified step by step guidance

1. Step 1: Understand the basic function of proteins. Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.
2. Step 2: Define channel proteins. Channel proteins are integral membrane proteins that form a channel to allow specific molecules or ions to pass through the cell membrane. They have a hydrophilic channel that certain molecules or atomic ions use as a tunnel through the membrane.
3. Step 3: Define carrier proteins. Carrier proteins are integral membrane proteins that bind to a specific molecule, change shape, and flip the molecule across the membrane. They are involved in the facilitated diffusion and active transport of molecules across the cell membrane.
4. Step 4: Compare the structures. Channel proteins have a pore for molecules to pass through, while carrier proteins do not have a pore but change shape to transport molecules across the membrane.
5. Step 5: Summarize the differences. In terms of structure, channel proteins form a tunnel that allows molecules to simply pass through, while carrier proteins bind to a molecule and change shape to shuttle them across the membrane.
