Definition: Electron capture is a type of radioactive decay where the nucleus of an atom absorbs a K or L shell electron and converts a proton into a neutron. This process reduces the atomic number by 1 and emits gamma radiation and a neutrino.
1) Energy is captured from sunlight by light absorbing molecules. Energy is transferred to electrons that enter an electron transport chain 2) water molecules are broken down into H+ ions, electrons, and oxygen molecules. 3) Energized electrons have 2 functions.ain function is to capture and transfer energy 1) CO2 is added to a cycle of chemical reactions to build larger molecules.Energy from light dependent reactions is used in the reactions 2) A molecule of simple sugar is formed.
