Opacity (optics) Opacity is the measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light. In radiative transfer, it describes the absorption and scattering of radiation in a medium, such as a plasma, dielectric, shielding material, glass, etc.

For every three turns of the Calvin cycle, three atoms of carbon are fixed from three molecules of carbon dioxide. In the carbon fixation stage, carbon dioxide is attached to RuBP by the enzyme rubisco. The resulting 6-carbon product quickly splits into two molecules of a three-carbon compound (3-phosphoglycerate). When three carbon dioxide molecules enter the cycle, six molecules of 3-phosphoglycerate are produced.
