Glucose (sugar) + oxygen = carbon dioxide + water + energy is the word equation for cellular respiration (as ATP). C6H1206 + 6O2 = 6CO2 + 6H2O + energy is the balanced chemical equation for this reaction (ATP). Glycolysis and the Kreb’s cycle, for example, are two steps of cellular or aerobic respiration.
The energy produced in this reaction is temporarily stored in adenosine triphosphate molecules. The cytoplasm of cells contains ATP.
The cellular respiration chemical equation is the inverse of the photosynthesis reaction in plants. Photosynthesis is the process through which plants convert carbon dioxide and water into glucose and oxygen.
