Q. In carbon cycle of nuclear fusion, acts as

UP CPMTUP CPMT 2007 Report Error

Solution:

Carbon cycle : cycle of nuclear reactions resulting in the formation of one helium nucleus from four hydrogen nuclei, with the emission of gamma rays , positrons , neutrinos and a large amount o f energy. The set o f reactions are as follows






The overall reaction can be written as

The carbon is reformHed at the end of the cycle and therefore acts as a catalyst. The carbon cycle occurs in stars hotter than the sun
