Question
* this s. What do the proteins involved in the electron transport chain do that will eventually be used to produce ATP? a. They pump H+ from outside the mitochondria to the inside b. They use substrate level phosphorylation to produce ATP e They pump H+ into the space between the mitochondrial d. They break pyruvate into smaller pieces e. Th ey absorb light and pass electrons onto reaction center complexes Which of the following is the reason why some organisms need oxygen for respiration? 9. a. So water can be created for other reactions b. Oxygen donates the electrons needed in respiration &It; is used to carry electrons to the electron transport chain d. It is used as a final electron acceptor in the electron transport chain e. It is used as a catalyst in reactions 10. In which of the following steps is CO2 not produced as a byproduct of aerobic 7 respiration? Glycolysis At wuse ,NADI b. c. Krebs cycle Conversion of pyruvate to Acetyl CoA before the citric acid cycle Both B and C 1 1 ferohic respirationExplanation / Answer
8) Option C is the correct answer.
Electron carriers in the electron transport chain in mitochondria pump H+ in the intermembrane space in mitochondria which creates a chemiosmotic gradient and is responsible for driving ATP synthase to produce ATP.
9) Option D is correct.
Oxygen is used as a final electron acceptor in electron transport chain, where it accepts electrons due to the difference in redox potentials of oxygen and electron carriers in the ETC.
10) Option A is the correct answer.
Glycolysis in the process in which CO2 is not produced.
