The bar graph shows the rate of dye color change in the two experimental conditions.
1 A) faster than in the experiment in which there was no cyanide. B) at the same speed as the experiment in which there was no cyanide. C) slower than in the experiment in which there was no cyanide. 2 A) increasing the amount of succinic acid available to the enzyme, succinic dehydrogenase (SDH). B) absorbing fumaric acid from the solution. C) acting as a co-factor to enhancing the action of the enzyme, succinic dehydrogenase (SDH). D) doing none of the above; cyanide did not affect the reaction. 3 A) by cyanide increasing the rate of succinic acid breakdown. B) by cyanide increasing the amount of FAD available. C) by cyanide enhancing the citric acid cycle. D) by cyanide inhibiting the electron transport system. 4 A) only the electron transport system. B) the electron transport system and the dye. C) only the dye. 5 A) were absorbed by the electron transport system, and this increased the rate of dye color change. B) were absorbed by succinic acid, and this increased the rate of dye color change. C) were absorbed by the dye, and this increased the rate of dye color change. D) were absorbed by the citric acid cycle, and this increased the rate of dye color change.
