When a cell needs energy, for example, to pump out molecules or to repair a broken micro machine, it can break down ATP, and use the chemical energy to do work and create change.
" That's because, in winter, life inside the pingo doesn't rely at all on solar energy -- it's only using chemical energy, " says microbiologist Dimitri Kalenitchenko of Norway's University of Tromso, who is leading the project.
And the other thing-there is research which suggests that it might be a factor in transforming the chemical energy we get from food into what is called heating energy, so in other words, it keeps us warm.
Not only is the food's chemical energy converted into kinetic energy for an athlete's movement, but nerves and emotional stress can cause issues with digestion and proper breathing, or even cause vomiting.
Wherever we go on Earth--even into what's seemed like the most hostile possible environments for life, as long as there is liquid water and some source of chemical energy we find life.
The amazing thing about your complicated, self-healing, blood-guzzling muscle tissues is that they turn chemical potential energy into mechanical energy, or movement, simply by doing two things — contracting and relaxing.
And you can get some of the things you need pretty easily. Like, in order to get oxygen for respiration, to unleash the chemical energy in your food, you just have to inhale.
