The small sausage-shaped structure where food is burned to release energy is called the mitochondrion. Often referred to as the "powerhouse of the cell," mitochondria generate adenosine triphosphate (ATP) through cellular respiration, utilizing oxygen and nutrients. This process is essential for providing energy for various cellular functions.
yes
Many substances can be burned to release heat energy, pretty much anything. However, water or ice is one that can not.
Biomass.
fuel
fats
fuels are burned to release the chemical energy
Ethanol releases about 21.1 megajoules of energy per liter when burned.
Because the body will have to release the fat for energy, which is then burned by mitochondria in the cells for energy to exercise.
Metabolism.
Fuels such as gasoline, coal, natural gas, and wood all release energy when they are burned. This energy is in the form of heat and light, which can be harnessed for various purposes such as heating, electricity generation, and transportation.
Petroleum energy is released through combustion, where the fuel is burned in the presence of oxygen to release heat energy. This heat energy is then used to generate electricity or power engines in vehicles and machinery.
Hydrogen gas provides the highest energy output per unit mass when burned, making it the most energy-dense fuel. It has a high energy-to-weight ratio, which means it can release large amounts of energy when combusted.
