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.

The steps in the cycle are as follows: 1  1. Grab: A five-carbon carbon catcher catches one molecule of carbon dioxide and forms a six-carbon molecule. 2  3. Leave: A trio of three carbons leave and become sugar. 3  4. Switch: Using ATP and NADPH, the three carbon molecule is changed into a five carbon molecule. 5. The cycle starts over again. The product. The carbohydrate products of the Calvin cycle are three-carbon sugar phosphate molecules, or 'triose phosphates' (G3P). Each step of the cycle has its own enzyme which speeds up the reaction. The Nobel Prize in Chemistry 1961 Melvin Calvin.
