Question

The simplest type of cell transport is _________________, in which molecules move from an area of _______________ concentration to an area of __________ concentration. Diffusion does not use ATP, so it is called _____________ transport. The movement of a solute from an area of low concentration to an area of high concentration requires __________ usage by _________ proteins. This form of transport is referred to as _______________ transport.
low; passive; diffusion; high; carrier; active; ATP.

Answer 1

Answer:

Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. There are different types of diffusion: simple in which the molecule passes directly through the phospholipid bilayer and facilitated which uses the integral membrane proteins as channels.
