Thermoregulation??

[Rofeki]

So i have a chemistry presentation or any chemical reaction i want. I want to do something that has to do with reptiles and amphibians. I always get confused on physical changes and chemical changes so is Thermoregulation a chemical change? If so, how? Any help would be much appreciated!!

Thermoregulation is an adaptation to ambient temperatures. Reptiles being ectotherms need to thermoregulate to reach and maintain their prefered boby temperatures. I am sure as thermoregulation plays a part in methabolic functions that there would be "chemical" changes within the specimen. But for the definition of thermoregulation it is a physical change in core body temperature. This is done by either basking or hiding from the heat source (sun in the wild, heat lamps in captivity). Basking to heat up hiding to cool down as they do not self regulate/maintain their body temperatures internally like mammals and birds do.

If you want to present something in reptiles that is a chemical chnage I would be looking at the production of D3 in some diurnal lizard. This is an internal chemical reaction from the intake of inert calcium from the diet which is turned into usable vit D3 triggered by exposure to UVB in aid of bone developement.
