Chapter 9 Cellular Respiration & Fermentation
Essential Question How do organisms obtain energy?
9.1 Cellular Respiration: An Overview
Learning Objectives 9.1.1 Explain where organisms get the energy they need for life processes. 9.1.2 Define cellular respiration. 9.1.3 Compare photosynthesis and cellular respiration.
Chemical Energy & Food Where do organisms get energy? Organisms get the energy they need from food. Cells break down food molecules gradually, capturing a small amount of chemical energy.
p. 251 Cellular Respiration Cellular Respiration? Process that releases energy from food in the presence of oxygen. 6O 2 + C 6 H 12 O 6 6CO 2 + 6H 2 O
p. 252 Cellular Respiration Oxygen & energy Stage Oxygen Location 1. Glycolysis Anaerobic ( without air ) Cytoplasm 2. The Krebs Cycle Aerobic ( in air ) Mitochondria 3. Electron Transport Chain Aerobic ( in air ) Mitochondria When oxygen is not present Enters anaerobic pathway called fermentation.

9.3 Fermentation
Learning Objectives 9.3.1 Explain how organisms get energy in the absence of oxygen. 9.3.2 Identify the pathways the body uses to release energy during exercise.
Fermentation Fermentation? Process of releasing energy from food molecules in the absence of oxygen by producing ATP. Glycolysis & NADH No oxygen = no electron transport chain NAD + quickly become NADH Fermentation removes H + and recycles NAD +
Fermentation Fermentation? Process of releasing energy from food molecules in the absence of oxygen by producing ATP 2 types of fermentation: Alcoholic Fermentation - Alcoholic beverages & rising bread dough Lactic Acid Fermentation - Humans, cheese, yogurt, pickles, & kimchi
Energy & Exercise Humans have 3 main sources of ATP: ATP already in the muscles ATP made by lactic acid fermentation ATP cellular respiration
Energy & Exercise Quick Energy ATP in muscles = few seconds of intense activity. Lactic acid fermentation = 90 seconds of ATP Lactic acid = byproduct & requires extra oxygen to remove
Energy & Exercise Long-Term Energy Cellular respiration = longer than 90 seconds Muscle & other tissue = 15-20 min of activity Stored molecules (fats) = after 15-20 minutes
