Scientists have long suspected that temperatures may vary inside individual cells‚ because thousands of biochemical reactions at the basis of life are constantly underway inside cells. Some of those reactions produce energy and heat‚ but some cells are more active than others and the unused energy is discharged as heat. Parts of individual cells also may be warmer because they harbor biochemical power plants termed mitochondria for producing energy. http://www.acs.org/content/acs/en/pressroom/
