      n     (Botany)   a series of reactions, occurring during photosynthesis, in which glucose is synthesized from carbon dioxide  
     (C20: named after M. Calvin, who elucidated it)

2    four thermonuclear reactions believed to be the source of energy in many stars. Carbon nuclei function as catalysts in the fusion of protons to form helium nuclei  
Carnot cycle  
      n   an idealized reversible heat-engine cycle giving maximum efficiency and consisting of an isothermal expansion, an adiabatic expansion, an isothermal compression, and an adiabatic compression back to the initial state  
cell cycle  
      n   the growth cycle of eukaryotic cells. It is divided into five stages, known as G0, in which the cell is quiescent, G1 and G2, in which it increases in size, S, in which it duplicates its DNA, and M, in which it undergoes mitosis and divides
