Study Guide Overview

This study guide covers cell membrane transport, focusing on the phospholipid bilayer structure (hydrophilic heads, hydrophobic tails, proteins) and transport mechanisms. It details active transport (primary/secondary), passive transport, endocytosis, and exocytosis. The sodium-potassium pump is highlighted as a key example.

Cell Membrane Transport: Your Ultimate AP Bio Review 🚀

Hey, future AP Bio master! Let's break down cell membrane transport, the 'public transit' system of the cell. This is a **** that pops up everywhere on the exam, so let's make sure you've got it down cold.


The Cell Membrane: The Gatekeeper 🚪

The cell membrane (or plasma membrane) is like the cell's security system. It's a flexible barrier that controls what enters and exits.
