How is light converted to cellular energy?
When light waves strike the pigments contained in the plastid, electrons become excited and move out of the chlorophyll molecule.
When light waves strike the pigments contained in the plastid, one phosphate is released from the ATP molecule
When light energy strikes the sugar molecule glucose, it degrades into three simple carbon sugars.
Light energy cannot be converted to cellular energy by living things. Only humans can do this with solar cells.
