Summary Introduction
To review:
The consequences of experiment in figure 9.9 in the presence of antimycin A drug.
Introduction:
Figure shows an experiment, which was performed to prove that a proton concentration gradient drove formation of adenosine triphosphate (ATP) in the chloroplasts. Chemiosmosis occurs after electron transport chain (ETC) occurs inside mitochondria, in which production of ATP takes place by influx of protons back into the matrix of mitochondria.
The antimycin A drug is known to block electron transport in the chloroplasts and mitochondria.

udent set up the apparatus shown below, one with germinating seeds and one with dry seeds. The
ssium hydroxide (KOH) in each tube will absorb any carbon dioxide in the test tube so that carbo
ide released will not affect the volume of gas in the test tube. This ensures that the volume of

From the information provided in the table, calculate the delta G knot prime and the Keq value at 298 K for the redox reaction that occurs in this bacterium’s electron transport chain.

In the final step, electrons from cytochrome c to O2 reducing it to H2O in complex IV, and four protons are transported from the intermembrane space to the matrix. b. In the first step, electrons from FADH2 are transferred in complex II to ubiquinone, which does not transport any proton across the inner mitochondrion membrane. c. In the second step, complex III transfers the electrons from ubiquinone to cytochrome c, and four protons are transported from the matrix to the intermembrane space. d. The complete oxidation of FADH2 causes transfer of 6 protons and yields two ATP.arrow_forward
