In the electron-transport chain, electrons are handed off from low reduction potential carriers to increasingly higher reduction potential carriers. At some steps this exchange of electrons is sufficiently exergonic to drive proton pumping. Based on this, explain why FADH2 results in less ATP generation per mole compared with NADH.

You have added a drug that prevents the transfer of electrons from the electron transport chain...

You have added a drug that prevents the transfer of electrons from the electron transport chain of cellular respiration to O2. What would happen to the level of activity in the electron transport chain. Explain your reasoning.

Which molecule(s) provide high energy electrons to the electron transport chain in oxidative phosphorylation? a. ATP b. NADH c. FADH2 d. a and b e. b and c For every molecule of pyruvate oxidized in aerobic cellular respiration ____________ is(are) produced. a. one ethanol and one CO2 molecule b. one acetyl CoA molecule c. one acetyl CoA and one CO2 molecule d. three ATP molecules

Active transport is the movement of materials from a high concentration to a low concentration, requiring the use of energy from the dephosphorylation of ATP molecules. True False 1 points QUESTION 2 How is a lipid different from a carbohydrate? Lipids are nonpolar. Lipids dissolve in water. A lipid is only made up of hydrocarbons. Lipids store genetic information. 1 points QUESTION 3 If you place a cell that has a 1.0M solution of glucose in a beaker...

(g) Within the electron transport chain, complex ____ represents the entry port for electrons from NADH while complex ____ represents the entry point for electrons from FADH2. Group of answer choices I; III II; III I; II II; IV III; IV (h) You have a solution that contains the pyruvate dehydrogenase complex and all of the enzymes of the citric acid cycle, but none of the intermediates of the citric acid. If you add 3.0 mM each of pyruvate, coenzyme...

Assuming the electron transport chain received electrons from NADH and FADH2 in a 3:1 ratio as the wild type for a particular organism, what would the consequences be of a change to a 1:1 ratio? Select all that apply.

Explain how the “slide” of electrons down the electron transport chain is coupled to the production...

Explain how the “slide” of electrons down the electron transport chain is coupled to the production of ATP by chemiosmosis.

The electron transport chain has two diffusible electron carriers, ubiquinone, which shuttles electrons to the third mitochondrial complex, and cytochrome c, which shuttles electrons to the last mitochondrial complex (see figure below). Would it be possible for cells to use only one of these two diffusible electron carriers to shuttle electrons at each of these two steps of the electron transport chain? Why or why not?
