- 2. Multiple ChoiceWhich of the following statements are false?Glycolysis can occur with or without oxygenGlycolysis is the first step in both anaerobic and aerobic respirationGlycolysis occurs in the mitochondriaGlycolysis produces 2 ATP, 2 Pyruvates, and 2 NADH
- 3. Multiple ChoiceWhat are the products (things that are made) in cellular respirationATPCarbon dioxide (CO2)WaterAll of the above
- 4. Multiple ChoiceGlucose is broken down into pyruvate in a process known asglycolysiselectron transportthe Krebs cyclephosphorylation
- 5. Multiple ChoiceWhat is the correct equation for cellular respiration?6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy6O2 + C6H12O6 + Energy -> 6CO2 + 6H2O6CO2 + 6H2O -> 6O2 + C6H12O6 + Energy6CO2 + 6H2O + Energy -> 6O2 + C6H12O6
- 6. Multiple ChoiceWhat is cellular respiration?the breakdown of glucose to release ATPthe breakdown of glucose to release NADHthe breakdown of glucose to release FADHthe breakdown of glucose to release carbon
- 7. Multiple ChoiceWhich of these molecules is released during the Kreb's cyclenitrogenoxygenhydrogen sulfideCarbon Dioxide (CO2)
- 8. Multiple ChoiceWhat is the main job of the electron carriers in cellular respiration?Transport electrons and hydrogen atoms to the electron transport chainCapture energy throughout the process of cellular respirationProvide the reactants for the process of cellular respirationPump positive hydrogen ions and shuttle electrons across the electron transport chain and contribute to chemiosmosis

- 11. Multiple ChoiceWhere does ETC occur?Mitochondrial matrixOuter mitochondrial membraneInner mitochondrial membraneCytosol
- 12. Multiple Choice
after strenuous exercise, a muscle cell would contain decreased amounts of ______ and increased amounts of ______ ____

- 13. Multiple Choicesite of the krebs cycle1234
- 14. Multiple ChoiceDuring chemiosmosisH+ ions serve as the final electron acceptora concentration gradient is generated when H+ ions are passively transported from the matrix to the intermembrane space of the mitochondrionenergy is released as H+ ions move freely across the mitochondrial membraneATP is synthesized when H+ ions move through a channel in ATP synthase
