Answer:
Electron transfer to from cytochrome c to molecular Oxygen in the process of oxidative phosphorylation
Explanation:
Cytochrome c is a protein which is involved in the electron transport chain for the production of ATP molecules during then process of respiration. It a soluble protein found in the intermembrane space of the mitochondria. It receives electrons from ubiquinone at Complex III of the electron transport chain and transfers this electron to molecular oxygen through its interaction with complex IV or cytochrome c oxidase, reducing molecular oxygen to water.
If the interaction of cytochrome c with cytochrome c oxidase is inhibited, the process of elctron transfer to oxygen will be inhibited and, so ATP synthesis will cease.
Ultimately, respiration will be inhibited resulting in death of the organism. For example, cyanide inhibits cytochrome c oxidase resulting in death of the organism poisoned with cyanide.
Answer: Which is the BEST explanation for the drastic decrease in the number of dolphins killed after 1975?
A Tuna fishing was banned in 1975.
B. Dolphins stopped swimming with tuna.
C. Economic and political pressures were brought against tuna fishermen.
D. Dolphin deaths and tuna catches were not considered important after 1975.
Explanation: Improvements in fishing gear and techniques discussed in Chapter 7, the mandatory observer program, and the kill quota were responsible for the dramatic decline in the number of dolphins killed by boats in the U.S. fleet.
