Chlorophyll is green because it reflects green wavelengths of light and these are what we see. Photosynthesis occurs in cell parts called chloroplasts that occur primarily in plant cells that are exposed to light. For each carbon atom that is released from the Calvin cycle in a high-energy carbohydrate molecule, one carbon dioxide molecule must enter the cycle. The term phosphorylation refers to the addition of a phosphate group to an atom or molecule. The addition of the phosphate involves the addition of large amounts of energy.
Some animals can see additional wavelengths.
For example, some insects can see ultraviolet light. One consequence of this is that the shorter wavelengths are more likely to be dangerous to living cells. Light energy is absorbed by electrons that supply energy for the formation of molecules of ATP and NADP-H which are used as temporary energy storing molecules. High energy electrons in Photosystem I are used to manufacture molecules of NADP-H. 31.
