active transport and passive transport. active transport requires energy and able to transport molecules from low concentration side to higher concentration side. passive is just like a tube that connects innner side and outer side. it requires no energy but unable to do like active transport does
The two types of membrane transport proteins include protein channels and carrier proteins.
protein channels and protein carriers by Michael Uko Biochemistry major.
Integral proteins( intermediate protein) and Periherial proteins.

The proteins are of two types Integral and peripheral.
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
A bilayer of phospholipids regulates cell traffic. There are five methods of transport across the membrane; diffusion, facilitated diffusion, active transport, co transport and endocytosis/exocytosis.
they pass through channels in the cell membrane
Facilitated transport.
Active Transport
The brain
a cell transports things across the cell membrane from areas of high concentration to ares of low concentration
Movement of water across a membrane is called OSMOSIS.
