ANAT3231 Lecture 02 Cell Compartments

Introduction

A major difference between eukayotes and prokaryotes is the presence of physical compartments (membrane bound) within the cell. These compartments allow the separation/specialization of processes within the cell.

There also exist within each of these physical compartments, functional compartments where specific processes may occur or are restricted too.

This lecture is an introduction to compartments within the cell and membranes. The key components are: cell compartments, membrane structure, membrane models, membrane specializations. The lecture slides and textbook alone contain enough information as an introduction to the subject for this level of study. If you are interested in further reading, I have also included below links to more detailed textbooks with further information and images. Please note this additional information is not necessarily examinable, but may be useful if you have not previously studied biology. The link below to lecture slides allows you to open and view the slides in your web browser or download the PDF document for later viewing/printing.
