Microbial Metabolism — Glycolysis, Fermentation, Respiration & Biosynthesis Explained | Chapter 3 of Brock Biology of Microorganisms Welcome to Last Minute Lecture , where we break down complex textbooks into clear and concise summaries. In this post, we’ll explore Chapter 3 of Brock Biology of Microorganisms , which introduces the fascinating and diverse metabolic strategies used by microorganisms. From energy production and redox chemistry to biosynthesis and nitrogen fixation, this chapter reveals how microbes power life in virtually every environment on Earth. 🎥 Watch the complete video summary here: This post expands on all the key metabolic concepts, making it perfect for exam prep, academic enrichment, or just a deeper understanding of microbial physiology. Core Concepts of Microbial Metabolism Metabolism encompasses all chemical processes that occur within a cell, divided into two major branches: Catabolism: Breaks down molecules to release energy (e.g., g...

Cellular Respiration and Fermentation — ATP, Glycolysis, and Energy Pathways Explained (Chapter 9) Welcome to Last Minute Lecture! This post covers the essential processes of cellular respiration and fermentation as presented in Chapter 9 of Campbell Biology . Learn how cells harvest energy from glucose, generate ATP, and survive when oxygen is scarce. Watch the full video summary below and subscribe for clear, chapter-by-chapter science explanations! Introduction: How Cells Extract Energy Cells rely on complex biochemical pathways to extract energy from organic fuels, primarily glucose, in order to synthesize ATP—the universal energy currency. Chapter 9 details three main stages of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation. It also explains how fermentation enables ATP production when oxygen is limited. Overview of Cellular Respiration Catabolic Pathway: Cellular respiration breaks down organic molecules, releasing energy...
