What is the most important distinction between the membrane transporters known as channel proteins and those known as carrier pr
-Dominant- [34]

Answer:

Channel proteins form hydrophilic channels to passively transport substances down the concentration gradient.

Carrier proteins bind to substances to transport them actively against the concentration gradient. They do not form channels.

Explanation:

Channel proteins are the membrane proteins that serve in transport of small polar molecules and/or ions by making a hydrophilic pore across the membrane. These molecules diffusion through the pore and exhibit facilitated diffusion.  

Carrier proteins are the membrane proteins that transport the substances across the membrane by binding to them. They do not form the hydrophilic channels. Carrier proteins serve in the active transport of molecules against the concentration gradient.

active transport and facilitated diffusion are two types of cellular transport which statement is true of both
Dovator [93]

Answer:

I believe the correct answer is both involve proteins in the cell membrane.

Explanation:

This is because Facilitated diffusion does not require any energy to transport molecules, while Active transport requires ATP. Facilitated diffusion transports molecules from an area of higher concentration to an area of lower concentration (or down a concentration gradient). Active transport moves molecules from an area of lower concentration to an area of higher concentration (or up a concentration gradient). Answer choice A is the only choice that makes sense.
