Cells generate energy from the controlled breakdown of food molecules. Learn more about the energy-generating processes of glycolysis, the citric acid cycle, and oxidative phosphorylation.
Autotrophs are organisms that capture energy from nonliving sources and transfer that energy into the living part of the ecosystem. They are also able to make their own food. Most autotrophs use the energy in sunlight to make food in the process of photosynthesis.
