- In order to improve their recovery after an intense work out or competition, many high-level athletes use "cool downs" to rapidly slow down their movements, by eating a snack, and breathing deeply. What choice below accurately explains how these steps aid cellular respiration? A. Eating a snack takes in more energy which converts to sugar needed by the body to produce oxygen to begin cellular respiration. B. Cooling down in this way they are able to take in oxygen and sugar, which allows their cells to produce energy through cellular respiration. C. Breathing deeply and eating a snack releases more carbon dioxide and sugar, which leads to more energy for cellular respiration to begin. D. Cooling down in this way they are able to take in carbon dioxide and water which allows their cells to produce energy through cellular respiration. 5.Why is phenolphthalein added to the beaker in the respiration experiment? a. It shows a color to let us know if the solution is acidic or basic. b. It takes part in the neutralization reaction. c. It speeds up the respiration reaction. d. It allows you to blow more air into the beaker during the experiment.Your graphs should have helped you learn about relationship between size and respiration; what is true? a. Respiration per gram of weight is higher in smaller animals. b. Respiration per gram of weight is higher in large animals. c. Respiration per gram of weight is the same for animals of all sizes.
- Which statement is an accurate comparison of aerobic and anaerobic respiration in humans? A: Aerobic respiration occurs in the cytoplasm and mitochondria, whereas anaerobic respiration occurs only in the cytoplasm B: Aerobic respiration primarily uses carbohydrates to produce energy, while anaerobic respiration uses lipids C: Aerobic respiration produced ATP as the primary energy molecules, while anaerobic respiration produces ADP D: Aerobic respiration requires enzymes to facilitate its biochemical reactions, whereas anaerobic respiration does not use enzymesWould the respiration rate be different for a person who had just exercised instead of sitting in the lab? a. No, the respiration rate would be the same. b. Yes, the respiration rate would be slower because the exercise slows respiration and oxygen uptake. c. Yes, the respiration rate would be faster since the person needed more oxygen while exercising.Scientists were studying the effects exercise (running on a treadmill) has on the amount CO2 production and breathing rates on humans. Their conclusion was that a person who just completed a bout of exercise would have higher CO2 production and increased breathing rates when compared to when they were sitting in a chair. They also found that CO2 production and breathing rates would increase the longer they exercised. Based upon what we know about cellular respiration and energy production, select the reason that best explains the results of the testing above, CO2 production increases because CO2 is being made in the electron transport chain to keep the electrons moving. Breathing rates will increase in order to get rid of the lactic acid from working muscles. CO2 production increases because more of this is made as a direct result of glucose being split for energy. Breathing rates will increase with exercise in order to supply the muscles with more O2. Ne

Reduced hemoglobin (Hb) concentration in blood so that the light intensity at the output decreases to the one tenth of input intensity? c.At the concentration you found in b, what is Ii / If for oxidized hemoglobin?You would expect decreased production of ATP in all of the following individuals except a. an individual with impaired ability to transport oxygen in the blood, such as a person with anemia. b. an individual with severe asthma. c. an individual in congestive heart failure. d. an athlete.In anaerobic respiration, lactic acid is released into the blood from skeletal muscle. When oxygen is available, most of the lactic acid is converted back to pyruvic acid and glucose in the A. liver. B. skeletal muscle. C. Heart. D. lung.
- Which of the statements is NOT TRUE about anaerobic respiration and fermentation? a. Anaerobic respiration has greater ATP output than fermentation. b.
