What is a major difference between facilitated diffusion and active transport?
question 30 options:

active transport moves substances against the concentration gradient.

active transport uses proteins in the process.

facilitated diffusion moves molecules through the plasma membrane.

facilitated diffusion requires large amounts of energy.

The correct option is A) Active transport moves substances against the concentration gradient.

Explanation:

Facilitated diffusion can be described as the type of diffusion which occurs with the help of other molecules. For example, when integral proteins help in the transport of a molecule through the cell membrane. Facilitated diffusion is a type of passive transport as it allows molecules to move from an area of higher concentration to an area of lower concentration along a concentration gradient.

Active transport is the movement of molecules against the concentration gradient from an area of lower concentration to the area of higher concentration and hence, require energy.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
