How many ATP are generated in the electron transport chain?

32 ATP molecules
Because FADH2 enters the chain at a later stage ( Complex II), only six H+ ions are transferred to the inter membrane space. This accounts for about two ATP molecules. A total of 32 ATP molecules are generated in electron transport and oxidative phosphorylation

Pro insulin undergoes extensive posttranslational modification along the production pathway .

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
