It binds itself to the receptors present on the surface of the cell membrane, which activates the enzymes present inside the cell.
The sun is extraordinarily hot because it is a star. Additionally, each star has its own unique, incredibly hot processes. These reactions are referred to as thermonuclear fusion. The Sun appears to be enormous in comparison to other stars due of its proximity to us. The Sun is a star of medium size. For instance, the following is a list of some of the biggest stars in our galaxy and their distance from the Sun: Mu Cephi is approximately 1500 times the diameter of our sun. The sun's core is so heated and pressurized that nuclear fusion occurs, converting hydrogen to helium. Nuclear fusion generates energy in the form of heat and photons (light)... Solar heat and light are sufficient to illuminate Earth's days and keep our planet warm enough to support life.
