Question
Chapter 11, Problem 49FB
Summary Introduction
To review:
The given blank space in the statement “_________ is a form of membrane transport that requires no direct energy input but does require a channel or a carrier.”
Introduction:
Passive transport is the mechanism during which the movement of substances occurs across the concentration gradient and the membrane. This transport mechanism does not involve any direct energy input. Simple diffusion and facilitated diffusion are the two types of passive transport.
