πŸ“š Quick Study Guide

  • βš›οΈ Cellular respiration is how cells generate energy in the form of ATP (adenosine triphosphate).
  • 🍎 The main stages of cellular respiration are glycolysis, the Krebs cycle (or citric acid cycle), and oxidative phosphorylation (electron transport chain).
  • πŸ’¨ Glycolysis occurs in the cytoplasm and breaks down glucose into pyruvate, producing a small amount of ATP and NADH.
  • πŸ‹ The Krebs cycle takes place in the mitochondrial matrix, further oxidizing pyruvate and producing more NADH, FADH2, and some ATP.
  • ⚑ Oxidative phosphorylation occurs in the inner mitochondrial membrane, where electrons from NADH and FADH2 are passed along an electron transport chain, ultimately leading to the production of a large amount of ATP.
  • β˜€οΈ Photosynthesis, primarily in plants, uses sunlight to convert carbon dioxide and water into glucose and oxygen. This glucose is then used in cellular respiration.
  • πŸ’ͺ ATP is the cell's "energy currency." It's a molecule that carries energy within cells for metabolic processes. Its hydrolysis (ATP β†’ ADP + Pi) releases energy.
