Today you’re going to learn about Biological Molecules in particular Inorganic Ions from the A-Level Biology AQA Specification and feel confident about exam technique! ✅ Watch all the videos for FREE on https://bit.ly/32OAe7d alongside our textbook and free flashcards. • A-Level Biology especially for AQA can be tough but fortunately we’ve made this tutorial to help you score the A* you need for questions on Inorganic Ions. ✅ • 📒The three main aims of this tutorial are to cover: 📒 • 1. Ionic Formation and Classification • 2. Inorganic Ions in the Body • 3. Biologically Relevant Inorganic Ions • Introduction (1:50) • An ion is a particle with an electric charge. Ions can be positive or negative. Ions can be organic or inorganic. Ions are formed when an atom transfers its electrons to another atom. • Inorganic Ions in the Body (2:49) • Inorganic have key biological functions. Ion concentrations vary. • Examples of Biologically Relevant Inorganic Ions (3:28) • Iron ions are key for oxygen transport in haemoglobin. • Hydrogen ions are important for regulating pH in organisms. pH control is important for many metabolic reactions. Hydrogen ions help control pH in digestion. Hydrogen ions also help in respiration. Sodium ions are key for co-transport. Sodium and potassium are key in the nervous system. Phosphate ions are found in phosphate groups. Phosphate groups are found in DNA, RNA, and ATP. Phosphate groups drive phosphorylation. Phosphate groups are found in phospholipids. • To catch our latest videos, subscribe and leave a comment below on a video you’d like us to record! • 👇 Subscribe to Study Mind with ONE CLICK👇 • 👇Revise with free past papers BY TOPIC for AQA A-Level Biology👇 • https://bit.ly/2mE065v • 👇Get personalised 1-1 Tutoring at £30ph for GUARANTEED improvement👇 • https://bit.ly/2mDXNzn • Tags: #AQABiology #ALevelBiology #StudyMind #InorganicIons
