2 Entry Task What is Bromothymol Blue (BTB)? An indicator solution that measures the ph of a solution, changing colors when the solution becomes acidic. How was BTB used during the exercise & cellular respiration activity? Breathed into the solution & the more CO2 caused the solution to change color quickly.

17 Cellular Respiration Cellular Respiration? Process that releases energy from food in the presence of oxygen. C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O + Energy p. 253

18 Cellular Respiration Cellular respiration modeled: Glucose (C 6 H 12 O 6 ) Oxygen (O 2 ) Mitochondria Electron carried in NADH Oxygen (O 2 ) Glycolysis Pyruvic Acid Krebs Cycle Electrons carried in NADH & FADH 2 Electron Transport Chain (ETC) Cytoplasm 2 ATP 2 ATP Carbon Dioxide (CO 2 ) 32 ATP Water (H 2 O) Enters anaerobic pathway called fermentation. p

19 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

20 Energy & Exercise Humans contain 3 main sources of ATP: ATP produced through cellular respiration. ATP already in the muscles. ATP made by lactic acid fermentation.

21 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

22 Energy & Exercise Long-Term Energy Cellular respiration = longer than 90 seconds Muscle & other tissue = min of activity Stored molecules (fats) = after minutes
