Which electron transport will lead to a greater release of energy that ultimately can be captured in the form of ATP? Where the Eo? is

+0.6 for the initial e- donor and +0.8 for the final e- acceptor.

-0.3 for the initial e- donor and +0.8 for the final e- acceptor.

-0.3 for the initial e- donor and +0.05 for the final e- acceptor.

-0.05 for the initial e- donor and +0.8 for the final e- acceptor.

-0.05 for the initial e- donor and +0.05 for the final e- acceptor.

Answer #1

Eo - E for electron acceptor - E for electron donor.

Difference between the  Eo for reaction 1 is = 0.8-0.6 = 0.2

Difference between the  Eo for reaction 2 is =  0.8 - (-0.3) = 1.1

Difference between the  Eo for reaction 3 is = 0.05 - (-0.3) = 0.35

Difference between the  Eo for reaction 1 is = 0.8 - (-0.05) = 0.85

Difference between the  Eo for reaction 1 is = 0.05 - (-0.05) = 0.1.

More the difference between the acceptor and donor electron potential more energy will be released.

hence answer is option B-  -0.3 for the initial e- donor and +0.8 for the final e- acceptor.

1. In the reoxidation of QH2 by purified ubiquinone-cytochrome c reductase (Complex III) from heart muscle, the overall stoichiometry of the reaction requires 2 mol of cytochrome c per mole of QH2 because: a. cytochrome c is a one-electron acceptor, whereas QH2 is a two-electron donor. b. cytochrome c is a two-electron acceptor, whereas QH2 is a one-electron donor. c. cytochrome c is water soluble and operates between the inner and outer mitochondrial membranes d. heart muscle has a high...

Under normal conditions, healthy heart cells (cardiac myocytes)prefer fatty acids as their fuel which ultimately results in energy being generated from oxidative phosphorylation through the electron transport chain. We will talk about how fatty acids are oxidatively metabolized in lecture 10. The condition ischemic cardiomyopathy is a result of narrowing of heart arteries which leads to decreased blood flow and a decrease in oxygen delivery to the muscle cells of the heart. In the ischemic heart, metabolism shifts from fatty...

The frequent consumption of sugar-sweetened soft drinks increases energy intake, which can lead to weight gain and obesity. In 2010, the worldwide burden of adiposity-associated cardiovascular diseases, cancers, and type 2 diabetes associated with consumption of sugar-sweetened was estimated to be 184,000 deaths. Whether regular consumption of soft drinks (total, sugar-sweetened, or artificially sweetened) is associated with greater all-cause and cause-specific mortality is uncertain, given that in-consistent findings were reported from previous prospective studies. The objective of the study was...
