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.

Cellular Respiration

Cellular Respiration? •  Process that releases energy from food in the

presence of oxygen. 6O2 + C6H12O6 6CO2 + 6H2O

p. 251

Cellular Respiration

Oxygen & energy 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
