Passive Transport - Simple Diffusion,Facilitated Diffusion,Ion Channels,Ionophores,Aquaporins

There are two types of transport mechanisms 

1.Passive Transport - it is of three types -

    i. Simple Diffusion

    ii. Facilitated Diffusion

    iii.Ion Channels

2.Active Transport - Click here for detailed notes

PASSIVE TRANSPORT

• This type of transport mechanism does not require energy.
• Movement of molecules occur along the concentration gradient.

Types of Passive Transport - 

Osmosis is a type of Simple Diffusion in which water molecules move from high concentration area to low concentration area through a selectively permeable membrane.
