CELLULAR RESPIRATION CELLULAR RESPIRATION What is it? Cellular respiration is the process by which cells break down glucose (a simple sugar) and other organic molecules to release energy in the form of ATP (adenosine triphosphate), which powers cell activities. Overall equation: C6H12O6 + 6O2 ⟶ 6CO2 + 6H2O + ATP (energy) Stages of Cellular Respiration 1. Glycolysis (in the cytoplasm) • Where it happens: Cytoplasm (outside mitochondria) • What happens: o One molecule of glucose (6 carbons) is split into two molecules of pyruvate (3 carbons each). o 2 ATP are used to start the process. o 4 ATP are produced (net gain = 2 ATP). o 2 NADH (electron carriers) are also produced. Summary of glycolysis products per glucose: • 2 ATP (net gain) • 2 NADH • 2 Pyruvate 2. Krebs Cycle (Citric Acid Cycle) (in the mitochondrial matrix) • Where it happens: Mitochondrial matrix • What happens: o Each pyruvate (3C) is converted to acetyl-CoA (2C) before entering the cycle. o Acetyl-CoA combines with oxaloacetate (4C) to form citric acid (6C). o Through a series of enzyme-controlled reactions, citric acid is broken down, releasing CO₂, ATP, NADH, and FADH₂. Summary of Krebs Cycle products (per 2 pyruvates): • 2 ATP • 6 NADH • 2 FADH₂ • 4 CO₂ (exhaled as waste) 3. Electron Transport Chain (ETC) & Oxidative Phosphorylation (in the inner mitochondrial membrane) • Where it happens: Inner mitochondrial membrane (cristae) • What happens: o NADH and FADH₂ donate high-energy electrons to proteins in the ETC. o As electrons move through the chain, protons (H⁺) are pumped across the membrane, creating a proton gradient. o This gradient powers ATP synthase, which makes lots of ATP (like a turbine powered by flowing water). o Oxygen acts as the final electron acceptor, combining with electrons and hydrogen to form water (H₂O). Summary of ETC products: • About 34 ATP • H₂O Total Energy Yield from One Glucose (Aerobic Respiration) • Glycolysis → 2 ATP • Krebs Cycle → 2 ATP • ETC → ~34 ATP Total: ~38 ATP (usually 36 in eukaryotes due to energy costs) Anaerobic Respiration (When Oxygen is Absent) If oxygen is not available, cells switch to fermentation: • Alcoholic Fermentation (yeast & some bacteria): pyruvate → ethanol + CO₂ • Lactic Acid Fermentation (muscles & some bacteria): pyruvate → lactic acid These processes only make 2 ATP per glucose, much less efficient than aerobic respiration. Key Takeaway: Cellular respiration is like the cell’s power plant: glycolysis breaks glucose into smaller pieces, the Krebs cycle extracts more high-energy electrons, and the ETC uses those electrons to generate the bulk of ATP. Oxygen is essential for the final step, which is why we need to breathe to stay alive.
