"when a biological molecule is oxidized, the electrons are often captured by nad, which is reduced to nadh. with that knowledge, identify if the substrate other than nadh or nad in each reaction is being oxidized or reduced."

Nadh and fadh 2 are important in cellular respiration because they deliver high-energy electrons to the electron transport system. electron transport produces atp molecule(s) per nadh molecule and atp molecules(s) perfadh 2 molecule.

Nadh and fadh2 are both electron carriers that donate their electrons to the electron transport chain. the electrons ultimately reduce o2 to water in the final step of electron transport. however, the amount of atp made by electrons from an nadh molecule is greater than the amount made by electrons from an fadh2 molecule. which statement best explains why more atp is made per molecule of nadh than per molecule of fadh2? a) the h+ gradient made from electron transport using nadh is located in a different part of the mitochondrion than the h+ gradient made using fadh2. b)fewer protons are pumped across the inner mitochondrial membrane when fadh2 is the electron donor than when nadh is the electron donor. c)it takes more energy to make atp from adp and pi using fadh2 than using nadh. d)there is more nadh than fadh2 made for every glucose that enters cellular respiration. e)fadh2 is made only in the citric acid cycle while nadh is made in glycolysis, acetyl coa formation, and the citric acid cycle.

Which statement best describes what happens during the redox reaction between nadh and complex i of the electron transport chain? a.nadh is oxidized by fadh2 which is then immediately oxidized in complex complex ii.b. nadh is oxidized as a pair of electrons, which are transferred to the etc and 4 four h+ are pumped into the intermembrane space.c. ubiquinone receives two electrons from nadh and then moves throughout the hydrophobic interior of the etc membrane where it is oxidized by complex complex ii.d. two electrons from nadh are used to reduce oxygen gas (o2), which picks up two h+ form from the matrix to produce water.
