1. Cellular respiration is the chemical opposite of photosynthesis. What is its basic chemical formula? 6 H2O(water) + 6 CO2 (carbon dioxide) --> C6H12O6(glucose) + 6 O2 (oxygen) 6 H2O(water) + 6 O2 (oxygen)--> C6H12O6(glucose) + 6 CO2 (carbon dioxide) C6H12O6(glucose) + 6 CO2 (carbon dioxide) --> 6 H2O(water) + 6 O2 (oxygen) C6H12O6(glucose) + 6 O2 (oxygen) --> 6 H2O(water) + 6 CO2 (carbon dioxide)
2. Cellular respiration is completely aerobic, meaning that every phase needs oxygen in order to take place. True False
3. Which isn't an end product of glycolysis? 2 water molecules 2 NADH 2 ATP 2 carbon dioxide molecules
4. The Krebs cycle occurs within the mitochondria of a cell. Which best describes the site of the Krebs (citric acid) cycle inside the mitochondria? Stroma Mitochondrial matrix Inner mitochondrial membrane Outer mitochondrial membrane
5. Before the Krebs cycle, pyruvate from glycolysis is attached to an enzyme that makes it easier to break down. Carbon dioxide is released and a molecule of NADH is formed. What name is given to the molecule that now enters the Krebs cycle? Phosphoglucoisomerase Acetyl CoA Acetyl CoB Phosphofructokinase
6. The final step in the process of cellular respiration is the electron transport chain (ETC). What best describes the first step in the electron transport chain? Energized electrons from NADH and FADH2 activate transport proteins. Electrons from NADH and FADH2 bond with hydrogen ions to form water molecules. Hydrogen ions diffuse through the membrane. Electrons in the inner membrane are energized by the Sun.
7. Once enough H+ ions have been pumped outside the membrane, they tend to move back inside the membrane. What is this random movement of particles from areas of high concentration to low concentration called? Active transport Diffusion Endocytosis Exocytosis
8. As the ions move back through the membrane, they flow through the enzyme that is the center of all cellular respiration. What is this important enzyme? Phosphoglucoisomerase Acetyl CoA ATP synthase Acetyl CoB
9. Two oxygen atoms enter the inner mitochondrial matrix at the end of the ETC. They bond with the electrons from the membrane and the protons that just passed through it to form what final product? Answer:
( Oxygen and hydrogen make...)
10. The electron transport chain is the only way that cells make ATP. True False
