Question | Answer |
---|---|
light absorbing pigment in plants and some protists that is required for photosynthesis; absorbs most wavelengths of light except for green | Chlorophyll |
process by which autotrophs, such as algae and plants, trap energy from sunlight with chlorophyll and uses this energy to convert carbon dioxide and water into simple sugars | Photosynthesis |
reaction taking place in the thylakoid membranes of a chloroplast during light dependent reactions where two molecules of water are split to form oxygen, hydrogen ions, and electrons | Photolysis |
energy storing molecule in cells composed of an adenosine molecule, a ribose sugar and three phosphate groups; energy is sotred in the molecule's chemical bonds and is used quickly and easily by cells. | ATP |
molecules that absorb specific wavelengths of sunlight | Pigments |
series of reactions during the light-independent phase of photosynthesis in which simple sugars are formed from carbon dioxide using ATP and hydrogen from the light dependent reactions. | Calvin Cycle |
series of proteins embedded in a membrane along which energized electrons are transported; as electrons are passed from molecule to molecule, energy is released | ETC |
molecule formed from the breaking off of a phosphate group for ATP; results in a release of energy that is used for biological reactions | ADP |
