Show Answer Correct Answer: B) VEIN. 9. Which one accurately describes the difference between respiration and cell respiration? A) Respiration produces glucose while cell respiration does not. B) Cell respiration is a process in cells where energy is made, while respiration is breathing. C) Respiration occurs in cells while cell respiration produces glucose. D) None of the above. Show Answer Correct Answer: B) Cell respiration is a process in cells where energy is made, while respiration is breathing. 10. Which of the following equation explains cellular respiration? A) Sugar+water $\rightarrow$ salt+sunlight. B) Sugar+oxygen $\rightarrow$ water+carbon dioxide+energy. C) Water+carbon dioxide+sunlight $\rightarrow$ sugar+oxygen. D) Sugar+energy $\rightarrow$ water+carbon dioxide+oxygen. Show Answer Correct Answer: B) Sugar+oxygen $\rightarrow$ water+carbon dioxide+energy. 11.

How do platelets work in the body (what is their job)? A) Attach to the injuries and release a chemical that allows the blood to clot. B) They help the white blood cells attach to the injury so the white blood cells can release a chemical that allow for blood to clot. Show Answer Correct Answer: A) Attach to the injuries and release a chemical that allows the blood to clot. 13. Air sac in the lung A) Alveolus. B) Antigen. C) Capillary. D) Epiglottis.

Show Answer Correct Answer: C) Stroke. 16. This best describes positive cooperativity of hemoglobin A) As 1 O2 binds to a heme group, it causes a sudden shift of polarity, attracting more O2. B) As 1 O2 binds to a heme group, a conformational change occurs, making it more likely for additional O2 to bind. C) As 1 O2 binds to a heme group, hemoglobin becomes slightly less hydrophilic. D) As 1 O2 binds to a globin group, the binding site of O2 within the molecule becomes more exposed. Show Answer Correct Answer: B) As 1 O2 binds to a heme group, a conformational change occurs, making it more likely for additional O2 to bind. 17.
