Isotopes are atoms of the same element that have the same number of nucleic protons, but different numbers of nucleic neutrons. This has the effect that they have a different mass number. However they have the same atomic number because that is a measure of how many protons are in the nucleus

The electron transport system in the light dependent reaction of photosynthesis is the one that is responsible for the production of electrons that are used as precursor for NADPH production. The NADPH and the other products that are made during the light dependent reaction are used during the dark reaction to produce sugar molecules. So, if the electron transport is disabled, glucose molecule will not be produced during the dark reaction.<span />
