Enzymes & Metabolism [IB Biology HL]

The topics in this video are cellular metabolism and enzyme function. Alongside energy production, we’ll look at the mechanisms that generate metabolic heat, helping animals regulate body temperature, as well as how metabolic pathways occur in both linear and cyclic pathways. We'll also examine how enzymes are regulated through competitive and non-competitive inhibition, feedback loops, and mechanism-based inhibition. By understanding these processes, we gain insight into both basic biological functions and how drugs or toxins can impact enzyme activity in living organisms. 0:00 - Introduction 0:59 - Intracellular and Extracellular Reactions 2:42 - Linear and Cyclic Metabolic Pathways 3:26 - Competitive Inhibition 5:54 - Non-Competitive Inhibition 7:07 - Feedback Inhibition 8:46 - Mechanism-Based Inhibition 10:04 - Summary More IB Biology Videos & Exam Questions can be found at: Revision Village - IB Biology https://www.revisionvillage.com
