In photosynthesis, carotenoids having more than seven conjugate double bonds, such as, carotenes and xanthophylls, play an important role by absorbing light energy. Chloroplast has a structure called chlorophyll which functions by trapping the solar energy and is used for the synthesis of food in all green plants. As a food coloring, chlorophyll is used to add a green color to pasta, the spirit absinthe, and other foods and beverages. What happens to the electrons that are removed from the water molecules?

Plants are unique among earthly creatures in their ability to create their own food through the process of photosynthesis. When chlorophyll absorbs light, a large fraction of that light energy is transferred directly to electrons in the chlorophyll molecule itself. Despite the fact that green plants play an important role in the amount of oxygen in the air we breathe, phytoplankton and cyanobacteria in the worlds oceans produce up to one-third of the amount of oxygen that we breathe. 38. Because nitrogen can move around in the plant, older growth often yellows more than the new growth.

Photosynthetic pigments can also inhibit photosynthesis when energy levels within the cell are too high. When pigments are extracted, the antenna complexes, reaction centers, and ETCs have been disassembled, so the energy is given off as fluorescence and/or heat. Plants use photosynthesis to convert sunlight into glucose. The chloroplast is a double membrane organelle that performs the function of photosynthesis of plant cells. The electron used in this process continues along the ETC to eventually aid in the production of NADPH. The electrons of the chlorophyll molecules become very excited. 1 What is the role pigments in photosynthesis?
