* Energy Release: Cellular respiration breaks down glucose (a sugar) and releases the chemical energy stored within its bonds. This energy is then captured in the form of ATP (adenosine triphosphate), the primary energy currency of cells.
* Breakdown of Molecules: The process involves breaking down complex molecules (like glucose) into simpler ones (like carbon dioxide and water). This breakdown releases energy.
* Oxidation: Cellular respiration is an oxidative process. It involves the loss of electrons from glucose, which are then used to generate ATP.
In contrast, a gathering process would involve building up complex molecules, requiring energy input. Photosynthesis, for example, is a gathering process where plants use sunlight to convert carbon dioxide and water into glucose, storing energy in the process.
