Bt corn is a genetically modified organism that contains a gene from bacteria that live in soil. this inserted gene allows the corn to kill the corn borer caterpillar

The inserted gene from the bacteria (Bacillus thuringiensis) produces a protein (Bt delta endotoxin) which kills the corn borer caterpillar by binding to the gut wall of the insects when the insects ingest a part of the plant that contains this protein. The insect would stop feeding immediately this protein binds to the gut wall of the insect, which leads to the eventual death of the corn borer caterpillar as the gut wall breaks down.

For each FADH2 that supplies electrons to the electron transport system, 2ATPs are synthesized. For each NADH that supplies electrons to the electron transport system, 3 ATPs are synthesized.

Explanation:

Both FADH2 and NADH are you reducing equivalents in that they give off electron in terms of hydrogen atom or a hydride ion.

Thus, in the inner membrane of the mitochondria where electron transport occurs, FADH2 gives off its hydride ion yielding 2 ATP molecules; while NADH gives off its hydride ions to yield 3 ATP molecules
