Answer: The electron transport chain is a group of proteins found in the inner membrane of the mitochondria of a eukaryotic cell. ... Using electrons, hydrogen ions, NADH, ADP, and oxygen, the electron transport chain is able to make energy in the form of ATP.
When the human body (its cells) is exposed to radiation (X rays and gamma rays), electrons are emitted from atoms and molecules. ... ・These radicals react immediately with surrounding atoms, causing abnormal chemical reactions (or, minor damage to localized areas of cells).
Uni cellular organisms remove their waste directly through the cell membrane by the process of diffusion while multi cellular organisms remove waste from excretion
