Cell Biology - Cell Biology | Cell Structure & Function

Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! In this foundational cell biology lecture, Professor Zach Murphy provides a detailed and organized overview of Cell Structure and Function, helping you understand the roles of key organelles and how they work together to maintain cellular homeostasis. We begin by breaking down the plasma membrane, emphasizing its phospholipid bilayer, membrane proteins, and selective permeability. From there, we explore major intracellular structures, including the nucleus, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, peroxisomes, and mitochondria—explaining their individual functions and how they coordinate to support growth, metabolism, protein synthesis, and waste management. The lecture also covers the cytoskeleton, detailing the roles of microfilaments, intermediate filaments, and microtubules in maintaining cell shape, intracellular transport, and cell division. We link structure to function throughout, making understanding how cellular dysfunction can lead to disease easier. This lecture is the perfect starting point for mastering cell biology and sets the stage for understanding more complex processes like signaling, transport, and division.
