How are the proteins used for active transport different from those used for facilitated diffusion?

The proteins for facilitated diffusion must attach to a carbohydrate to work.

The proteins used in facilitated diffusion create larger openings in the cell membrane.

The proteins involved in active transport must be powered by ATP to work.

The proteins that carry out active transport move only the largest molecules.

We will work through the problem. Do you know how active transport differs from facilitated diffusion?

You copied this question from http://answers.yahoo.com/question/index?qid=20120403152145AAcg7px. And Facilitated diffusion is passive transport in which larger molecules are transported through trans-membrane proteins and requires no energy . They go from high to low concentration because of this was provided as answer. Always quote any site used. .

no its actually a question from a test... @lanre
