Unformatted text preview: Chapter 8 Harvesting Energy: Glycolysis and Cellular Respiration • 8.1 How do cells obtain energy? • 8.2 How is the energy in glucose captured during glycolysis? • 8.3 How does cellular respiration capture additional energy from glucose? • 8.4 Putting it all together 8.1 How Is Glucose Metabolized? • Cellular Respiration: C 6 H 12 O 6 + 6 O 2-> 6 CO 2 + 6 H 2 0 + chemical and heat energy • Cellular respiration is about 40% efficient • Gasoline motors are about 25% efficient 8.2 How Is the Energy in Glucose Captured During Glycolysis? • Glycolysis is believed to be one of the most ancient chemical pathways because it is used by every living organism on the planet. • It only produces 2 ATP and 2 NADH • But it doesn’t use oxygen G3P molecule is the same one in photosynthesis Net gain of 2 ATP and 2 NADH A glucose molecule is energized by the addition of a high-energy phosphate from ATP....
