Fats store the most energy. 80 percent of the energy in your body about 146 ATP from a triglyceride Proteins are least likely to be broken down to make ATP. amino acids not usually needed for energy about the same amount of energy as a carbohydrate Calorie= amount of heat energy required to raise the temp of one kg of water by 1 degree celcius

Main Idea #3: A few types of organisms do not need sunlight and photosynthesis as a source of energy Some organisms live in places that never get sunlight. In chemosynthesis, chemical energy is used to build carbon-based molecules. similar to photosynthesis uses chemical energy instead of light energy
