Which energy release mechanism primarily drives stellar nucleosynthesis in main sequence stars?

💡 Explanation

The proton-proton chain reaction converts hydrogen to helium, releasing energy because mass is converted to energy via nuclear fusion, therefore stellar hydrogen consumption is via fusion rather than, for example, fission or radioactive decay.
