Yeasts convert sugars into alcohol and CO2.
anaerobic respiration
Yeast use fermentation (alcoholic fermentation). This produces carbon dioxide, alcohol, and some energy.
Carbon Dioxide and a kind of Alcohol called Ethanol.
Respiration
aerobic
ATP
Calories don't "produce" energy; calories are a UNIT OF ENERGY.
Computers do not produce energy, they use/consume energy.
Energy is stored as chemical energy. This energy is in chemical bonds
The sun produce light and nuclear energy
Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose, which has energy stored in its chemical bonds. You can think of glucose as a kind of cellular piece of coal: chock-full of energy, but useless when you want to power a stereo. Just as burning coal produces heat and energy in the form of electricity, the chemical processes of respiration convert the energy in glucose into usable form.
