Cell 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…

Prior to teaching cell transport in my Biology class, I like to take a deep dive into the cell membrane, its function, structure, and behavior. I truly feel that an extra few days to establish a strong understanding of the cell membrane helps my students better understand cellular transport. Today on the blog, I am ... Read more
