WebNov 15,  · the pigment molecule does it process faster. Wiki User. ∙ This answer is. WebThe additional pigments would provide protection to the chlorophyll molecule against photo-oxidation. More pigments will capture more energy to start the initial reactions, which is not possible due to a single pigment. Some of these additional pigments act as co-enzymes for chloroplasts, helping in their metabolic activities. WebNov 16,  · The green pigment in plants that absorbs light energy (energy from the sun) is call chlorophyll. What is the name of the molecule that absorbs light? The answer is chlorophyll is the pigment in. WebHow do pigments absorb and reflect different wave lengths of light? Question Date: Answer 1: Pigment molecules, just like any other molecule, have electrons that can "occupy" different energy levels. It turns out that in pigment molecules, the differences between certain energy levels correspond to the energies associated with.
