Membrane transport

If a cell were a house, the plasma membrane would be walls with windows and doors. Moving things in and out of the cell is an important role of the plasma membrane. It controls everything that enters and leaves the cell. There are two basic ways that substances can cross the plasma membrane: passive transport, which requires no energy; and active transport, which requires energy.

This is a re-posting of the notes I originally posted on reddit from a general cell biology class I took in spring 2011. I re-scanned them after signing all of them at the suggestion of another red…

This document discusses transport across membranes, including three categories of transport mechanisms: passive transport, active transport, and endocytosis/exocytosis. Passive transport relies on diffusion and concentration gradients and includes simple diffusion, facilitated diffusion, and osmosis. Active transport uses energy to move molecules against concentration gradients, including primary and secondary active transport. Endocytosis imports materials into cells using mechanisms like…

The cell membrane is a phospholipid bi-layer into which proteins, glycoproteins, and glycolipids are ingrained. The cell membrane is also known as plasma membrane or plasmalemma. This membrane separ...

Plasma membrane is an extremely thin line making it very difficult to study. The major problem is the separation of membrane from the p...

The Biological Membranes page details biological membranes and the various mechanisms used in transport across membranes.
