Active transport differs from passive transport in that active transport

Read the following statements regarding porins and select the correct option given below:
$I$. Porins are transport proteins.
$II$. Channel proteins are a type of transport protein,which are usually gated.
$III$. Carrier protein binds the particular solute to be transported.
$IV$. Particular solute is delivered to the other side of the membrane by carrier proteins.

Facilitated diffusion in cells is brought about by . . . . . . in the cell membrane.

In .......... both molecules cross the membrane in the same direction.

Match the following columns:

Column-$I$	Column-$II$
$(A)$ Movement of ions into or out of the cell	$(1)$ Diffusion
$(B)$ Outward movement is	$(2)$ Flux
$(C)$ Inward movement is	$(3)$ Efflux
$(D)$ Passive uptake	$(4)$ Influx

Given below is a table. Fill in the gaps.

Property	Simple Diffusion	Facilitated Transport	Active Transport
