2013 Bio Aims Study Guide
In this topic, we will learn about vesicular trafficking, endocytosis and exocytosis and gain an introduction to cellular signal transduction mechanisms (also known as cell signalling). We will also look at the most important methods by which cells communicate, discussing how cells send signals and interpret the signals they receive. We will try to understand the biochemistry of phospholipids and how they are organized into membranes. We will also differentiate among diffusion, facilitated transport, facilitated diffusion, osmosis, and active transport. We will describe solution and solute movement in and out of a cell under hyperosmotic, hypoosmotic, or isoosmotic conditions. We will explain and give examples of endocytosis, phagocytosis, pinocytosis, receptor-mediated endocytosis and exocytosis. Finally, we aim to understand the importance of selective permeability in biological systems.
