Exam points
identify cristae and the inner mitochondrial membrane as the electron-transfer site
trace electrons and proton pumping from reduced NAD or FAD through the transport chain
explain ATP synthase action and oxygen as the final electron acceptor forming water
Animals use aerobic and anaerobic respiration to produce ATP.
Aerobic respiration has three stages where reactions occur between enzymes and substrates.
Hydramethylnon is an insecticide that is used to treat termite infestations.
Hydramethylnon inhibits the electron transport chain.
Which row of the table shows the expected changes caused by hydramethylnon?
The only correct answer is B A is not the correct answer as lactate production does not decrease C is not the correct answer as lactate production does not decrease D is not the correct answer as oxygen consumption does not increase.
