Answer 1

1. During electron transport chain the electrons are passing through the electron transport chain . It mainly happens in three way glycolysis, krebs cycle and electron transport chain. The final electron acceptor is oxygen and it with electron and proton it forms water. Most of eukaryotic have mitochondria which cell produce ATP in form of energy. Pyruvate is transported in mitochondria and excrete carbon dioxide in form of acetyl COA.

So Carbon dioxide , water and oxygen are the product of electron transport chain but urea is not the end product of electron transport chain.
