⭐️ Check out our website https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. The four main types of biological molecules. * An introduction to carbohydrates, lipids, proteins, and nucleic acids. * The role of carbon in forming complex organic molecules. * The elemental composition of each type of biological molecule. 2. The concepts of monomers and polymers. * The definition of a monomer with examples like monosaccharides, amino acids, and nucleotides. * The definition of a polymer with examples like polysaccharides, polypeptides, and polynucleotides. * An explanation of polymerisation. * A clarification of why lipids are not considered true polymers. 3. How polymers are formed and broken down. * An explanation of condensation reactions, which join monomers and release water. * An explanation of hydrolysis reactions, which use water to break down polymers. *** CHAPTERS *** 0:00 Introduction to Biological Molecules 0:25 The Four Main Types of Biological Molecules 0:37 Carbon and Organic Molecules 1:12 Elemental Composition of Biological Molecules 1:51 What are Monomers and Polymers? 3:32 How Condensation Reactions Work 4:27 How Hydrolysis Reactions Work *** PLAYLISTS *** https://youtube.com/playlist?list=PLidqqIGKox7VzYfPIVt8T09xOLNcolCe4&si=8JmDajxjtba6rdc3 https://youtube.com/playlist?list=PLidqqIGKox7UZ3mWhbHv2aA_1vnbsfRPq&si=q3hEKdA4v7kbfwMe https://youtube.com/playlist?list=PLidqqIGKox7XPh1QacLRiKto_UlnRIEVh&si=orIUwL3o2jOoiYjT https://youtube.com/playlist?list=PLidqqIGKox7X5UFT-expKIuR-i-BN3Q1g&si=DcihOwUkd9oWbbdp https://youtube.com/playlist?list=PLidqqIGKox7WeOKVGHxcd69kKqtwrKl8W&si=Y8MsO-FK948jnxpS https://youtube.com/playlist?list=PLidqqIGKox7UVC-8WC9djoeBzwxPeXph7&si=-7i5Iq7yOeJrhtu6 https://youtube.com/playlist?list=PLidqqIGKox7VKJD2WxRhoKaI6JGLVean8&si=NH_Q1ujhVgACM2FU #Alevel #Biology #study #revision #school #exam #AQA #OCR #Edexcel #IB #AP
