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.
Answers.comÂ® is making the world better one answer at a time. during Calvin Benson cycle carbon dioxide from the air is used to produce glucose and other compounds.
Best Answer: It's the light-independent reaction involved in photosynthesis. It uses ATP molecules and NADPH molecules to convert carbon dioxide into glucose(a simple sugar). It is also known as the Calvin-Benson(the two scientists that discovered it) Cycle or simply as the light-independent reaction in photosynthesis. The ATP and the NADPH comes from the light-dependent reactions in photosynthesis, which turns water into oxygen. Source(s): ATP-Boy Â· 8 years ago.
