- A. Lipid
- B. Comer
- C. Charge pores
- D. Carbohydrates
Explanation
Channel proteins, gated channel proteins, and carrier proteins are three types of transport proteins that are involved in facilitated diffusion. A channel protein, a type of transport protein, acts like a pore in the membrane that lets water molecules or small ions through quickly.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
