Cellular Respiration There are 2 different types. . . 1. 2. Aerobic = using oxygen Anaerobic = not using oxygen
There are 2 types of cellular respiration. Aerobic vs. Anaerobic • Aerobic respiration – uses oxygen and creates 36 ATP molecules at a time. • Anaerobic respiration (without air) – does not use oxygen, it only makes 2 ATP at a time and creates extra waste products.
Anaerobic Respiration = No oxygen = Fermentation Alcohol fermentation – Glucose without oxygen produces 2 ATP, alcohol & CO 2 & water. Lactic acid fermentation – Glucose without oxygen produces 2 ATP, lactic acid, CO 2 and water.
AEROBIC RESPIRATION ANAEROBIC RESPIRATION Uses Oxygen Produces 36 ATP per cycle Occurs in the mitochondria Is the “norm” for human being cells. 5. Only produces the waste products of CO 2 and H 2 O 1. Does NOT use oxygen 2. Produces only 2 ATP per cycle 3. Occurs in the cytoplasm 4. Occurs during strenuous exercise in humans. 5. Produces lactic acid/alcohol in addition to CO 2 and H 2 O. 1. 2. 3. 4. BOTH Aerobic and Anaerobic Respiration 1. use glucose 2. make ATP 3. produce CO 2 and H 2 O
Compare and Contrast the two types of Cellular Respiration
Critical Thinking Question • Why do you feel the burning sensation in your muscle during rigorous physical activity? Your answer should reference/include the breaking down of glucose without oxygen. _____________________________________________________ _____________________________________________________ _______________________
