If this is true and false, the answer is true. if not, please elaborate, hope this helps.
Answer:
Oxidative phosphorylation that generates most of the ATP is blocked, and oxygen cannot accept the electrons from NADH.
Explanation: Sorry this is late and may be wrong but it is my best guess and here is why:
Potassium cyanide blocks the ETC where the majority of ATP is produced. The ETC is a oxidative phosphorylation process where oxygen is needed as the final electron acceptor of NADH.
The first answer can be eleminated because oxidative phosphorylation produces the most ATP.
The second answer can be eleminated because chemiosmosis does not generate ALL the ATP during cellular respiration, but does produce most of it. Still they worded it as an "all or nothing" type of question so I don't think it is correct.
The fourth answer may not be correct because NAD does not pass on an electron to NADH. Instead, NADH donstes electrons to the ETC and is then turned into NAD. So the process listed is technically backwords.
Sorry I can't be sure about the answer but this is how I broke it down.
I think somewhere around two so maybe two or three
The answer is alveoli.
The bronchi conduct air to the lungs. They branch into secondary bronchi, which further branch into tertiary bronchi. They divide into small bronchioles. Bronchioles divide into terminal bronchioles, they into respiratory bronchioles, and later into alveoli. The alveoli are places where gas exchange occurs.
