Why was this a bad ie fatal idea?
Why was this a bad (i.e., fatal) idea? Because the energy was not used to synthesize ATP and was instead dissipated as heat, and the subject developed uncontrollable fevers.
Which of the following complexes does not pump any protons across the inner mitochondrial membrane?
NADH-Q oxidoreductase, succinate-Q reductase, Q-cytochrome c oxidoreductase, and cytochrome c oxidase are also called Complex I, II, III, and IV, respectively. Succinate-Q reductase (Complex II), in contrast with the other complexes, does not pump protons.
Is ubiquinone an electron carrier?
Ubiquinone has a higher reduction potential than the NADH-Q reductase. Hence NADH-Q reductase acts as both an electron carrier and a proton pump. Ubiquinone is an electron carrier only; it is not a proton pump. Therefore, ubiquinone does not increase the H+ concentration in the intermembrane space.
How many ATP are made in electron transport chain?
34 ATP
Why does the electron transport chain make the most ATP?
During this process electrons are exchanged between molecules, which creates a chemical gradient that allows for the production of ATP. The most vital part of this process is the electron transport chain, which produces more ATP than any other part of cellular respiration.
Why does FADH2 contribute less to the production of ATP than NADH?
Correct answer: FADH2 produces less ATP then NADH because the electrons for FADH2 are dropped off at the second protein of the electron transport chain. As a result, the electrons from FADH2 do not pump as much electrons across the membrane as NADH.
What molecule is most helpful with synthesizing ATP?
NADH is used for the ETC and ATP synthesis.
Why does NADH produce more energy than FADH2 quizlet?
Why does NADH produce more energy than FADH2? NADH has a high free energy and can be oxidized more readily than FADH2. In order to completely oxidize glucose, it takes two turns of the citric acid cycle, which yields a net of 2 ATP, 6 NADH, and 2 FADH2.
Which of the following would not slow down the electron transport system’s production of ATP?
Which of the following would NOT slow down the electron transport system’s production of ATP? Increase the pumping of hydrogen ions into the intermembrane space of the mitochondria. no oxygen is available.
Why does lack of oxygen result in the halt of ATP synthesis?
Why does lack of oxygen result in the halt of ATP synthesis? The chain shuts down and can no longer pump hydrogen ions across the membrane, and the proton gradient cannot be maintained. This causes the proton gradient to break down, stopping ATP synthesis.
Which of the following pathways of cellular respiration produces the majority of ATP?
glycolysis
