How are the proteins used for active transport different from those used for facilitated diffusion? a: the proteins for facilitated diffusion must attach to a carbohydrate to work. b: the proteins used in facilitated diffusion create larger openings in the cell membrane. c: the proteins involved in active transport must be powered by atp to work. d: the proteins that carry out active transport move only the largest molecules.

If we talk about active transport mechanisms, it means that the proteins basically require the use of the energy, that energy is usually in the form of adenosine triphosphate (ATP). but if we talk about the facilitated diffusion, then the solute can move from the regions of lower concentration to the region of higher concentration. In this way, the proteins used for active transport different from those used for facilitated diffusion.

c-reactive protein (crp) is an acute phase protein belonging to pentraxin family of proteins, whose levels increases 1000-fold or more in concentration in blood during the occurrence of an injury, inflammation or tissue death.

the answer is b: 1.4 km/hr
