Question
Q03.3. Recall that in cellular respiration, the processes of glycolysis, pyruvate processing, and the citric acid cycle precede the electron transport chain. What is produced by these three prior processes that is used by the electron transport chain? (Hint: Click here to see an overview of the major processes in cellular respiration.) Each of the three processes produce ATP, which carries potential energy to the ETC. O Each of the three processes produce protons that the ETC pumps into the intermembrane space O Each of the three processes produce NADH, which carries potential energy to the ETC Each of the three processes produce FADH2, which carries potential energy to the ETC Q3.4. In one of the reactions in the electron transport chain, coenzyme Q (i.e., "Q") transfers electrons to Complex Ill. Which molecule is reduced and which is oxidized in this reaction? O Complex Ill is reduced because it loses electrons, and Q is oxidized because it gains electrons O Complex IlIl is oxidized because it loses electrons, and Q is reduced because it gains electrons. Complex Ill is reduced because it gains electrons, and Q is oxidized because it loses electrons. Complex IlIl and Q are both oxidized because electrons are moved from one molecule to the other Q3.5. Which of the following does NOT store potential energy that is usable by a cell? ATPExplanation / Answer
Q. 3.3
All of these three processes produce proton which are released into inter membranes space and prosuce a Proton Motive Force which produce ATP when proton move into inner membranes through oxysomes. Option B is correct.
Q. 3.4.
When electrons are transferred to Complex III from Ubiquinone then Ubiquinone is oxidised by losing electron and Complex III is get reduced by accepting electrons. Option C is correct.
