Rotenone, a toxic compound isolated from plants, strongly inhibits the transfer of electrons from iron-sulfur centers in Complex
Darya [45]

Answer:

(A) It prevents electron flow from the iron-sulfur centers in complex 1 to the ubiquinone. Due to reduction in electron transfer rate, there is a decrease in the production of ATP which is dangerous for some insects and fish over time.

(B) It also prevents electron flow from cytochrome b to cytochrome c1 at the complex III which leads to QH2 accumulation. If oxidized Q is not present, these is alteration of electron flow and the production of ATP is altered.

(C) Rotenone only prevent electron transfer into the chain at Complex 1  but it does not affect electron transfer at Complex II. Although there is slow ETC, it does not stop completely. However, Antimycin A prevents the oxidation of QH2, the final electron acceptor crom complex I and complex II. Thereby, stopping the production of both ETC and ATP. It can be concluded that antimycin A is a more potent poison.

Explanation:

Rotenone prevents electron flow from the iron-sulfur centers in complex 1 to the ubiquinone. Due to a reduction in electron transfer rate, there is a decrease in the production of ATP which is dangerous for some insects and fish over time. Antimycin A also prevents electron flow from cytochrome b to cytochrome c1 at the complex III which leads to QH2 accumulation. If oxidized Q is not present, there is an alteration of electron flow and the production of ATP is altered. Antimycin A is more potent than rotenone.

Mountains formed by two colliding continents often contain marine _______ rock
stealth61 [152]
<span>The correct answer is Marine Sedimentary Rock. This means that when they collide, usually mountains come from out of the sea and move vertically up. This means that sedimentary marine rocks eventually become non-marine rocks since they're not in the sea anymore so they can be found on such mountains.</span><span />
