  1. Cellular Respiration 7.4 Anaerobic Respiration

  2. Anaerobic Respiration • Recall anaerobic respiration occurs in the _____________________of _________ • Two methods- - • Both methods begin with __________________

  3. Alcohol Fermentation • Starts with __________________ • Glucose is metabolized to ______________________ • A net of ________ ATP is made • During alcoholic fermentation • _____________________ is ________________ to form _____________________ • ________________________ is released • ________________ is recycled so ____________________ can continue • ___________________ do this • Leavened bread • Sparkling wine

  4. Lactic Acid Fermentation • Starts with ____________ • Glucose is metabolized to ______________________ • Pyruvate is reduced to form _________________________ • _________________ transfers H+ ions to ________________ regenerating NAD+ • A net of _____ ATP is made • No _____________ is released • Muscle cells have the ___________________to do this, but _________________ cells do not • Muscle cells can survive _______________ periods of oxygen _________________, but brain cells cannot • Lactic acid “_____________” in muscles

  5. Maximum Oxygen Uptake • Aerobic _____________________: measure of the ability of the heart, lungs, and bloodstream to supply __________ to the cells of the _______________ during physical activity • A _______________________ rate at which an individual can consume __________ during maximal __________________

  6. Exercise and VO2 max • Moving from rest to exercise _______energy requirements • Metabolism __________________ in direct proportion to _______________ of work • As demand for energy ______________________ so does ___________________ consumption (remember the role of oxidation to produce ATP to do work) • VO2 eventually peaks = • VO2 may remain _____________________at max or drop slightly even through work _________________ continues to increase • Average VO2 max is • Top athletes’ VO2 max is

  7. Supplements and Toxins • Creatine phosphate • donates its high energy ____________________ to the production of ____________ Creatine phosphate + ADP ↔ creatine + ATP • increase in ______________ may help to store creatine phosphate in muscle cells (creating a ____________________ of phosphate ready for ATP production) • potentially also acts as a ___________________ in muscle cells against _____________________

  8. Carbon ________________________ (CO) • combines with ________________________ preventing ________ from binding with red blood cells • affinity between hemoglobin and CO is about ______________ times __________________ than the affinity between hemoglobin and O2 • hemoglobin will bond with _________ before it will with _______ • No oxgyen available means the __________ ______________________ • Low ATP production results in cell ____________

  9. Cyanide and Hydrogen Sulfide • inhibit oxygen _______________________ by __________________________ • Stopping _______________ _________________
