What would happen if complexes I-IV of the electron transport chain pumped protons in the opposite direction? a. Too much ATP would be synthesized.
b. None of the other answer options is correct.
c. No ATP would be synthesized.
d. There would be too many electrons in the mitochondrial matrix.

The correct answer is - c. No ATP would be synthesized.

Explanation:

In the electron transport chain there are four complexes, complexes I-IV, pumps the protons from the matrix of the mitochondria into the intermembrane space. This is the downhill movement of the electrons that helps in synthesizing the ATP molecules.

If the complexes move or pump the electron uphill or against the gradient there would be no ATP formation as there would be no interchange of proton and electron interchange.

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.

and after water is usually warmed by the sun the water temperature raises and then evaporates .
