A. In the electron transport chain, a series of reactions move electrons through carriers.

B. The products of the electron transport chain are H2O and either NAD or FAD.

E. The electron transport chain is a series of oxidation-reduction reactions that occur in the inner mitochondrial membrane.

Explanation:

the best suitable statement is it transfers energy stepwise from one compound to another, The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons are transferred from one member of the transport chain to another in a series of redox reactions.

Answer from: shawny9979

The correct statements are: a), b) and e)

Explanation:

The high energy electrons are released from NAD and FAD and move along the electron transport chains, these are in the inner membrane of the mitochondria. As the high energy electrons are transported along the chains, part of their energy is captured. This energy is used to pump hydrogen ions (from NAD and FAD) through the inner membrane, out of the matrix into the intermembrane space. The electron transport chain serves the sole purpose of transporting protons from one side of these membranes to the other. The protons, thus, are concentrated on one side of the membrane. ATP synthase acts as a channel protein, helping hydrogen ions cross the membrane. It also acts as an enzyme, forming ATP from ADP and inorganic phosphate. After passing through the electron transport chain, the "spent" electrons combine with oxygen to form water. This is why oxygen is needed; in the absence of oxygen, this process cannot occur.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.
