Examples of Transport Across the Cell Membrane
Here are real-life examples of different kinds of transport happening in the body:
- Simple diffusion: Exchange of carbon dioxide and oxygen across the lipid bilayer.
- Facilitated diffusion: Transportation of glucose via a glucose transporter.
- Osmosis:The movement of water across the cell membrane.
- Primary active transport: Transportation of Na+ and K+ ions from inside to outside of the cell and from outside to inside of the cell, respectively.
- Secondary active transport: Transportation of glucose against a concentration gradient via a sodium-glucose co-transporter.
Transport Across Cell Membrane
Transport across the cell membrane is a special process that occurs via the cell membrane. The cell membrane keeps the internal and external environment separate and allows only specific molecules to transport across it. Transportation of molecules occurs via a specialized process known as active and passive transport. The selection of a molecule transporter depends on the molecule to be transported.
In this article, we will discuss transport system types, mechanisms of transport, active transport, passive transport, bulk transport, examples of transport, and factors influencing these transports.
