During photosynthesis and cellular respiration operation energy is?
During photosynthesis, energy is absorbed from sunlight and used to convert carbon dioxide and water into glucose and oxygen. This process stores energy in the chemical bonds of glucose.
During cellular respiration, energy is released from glucose molecules by breaking down glucose and combining it with oxygen. This process occurs in the presence of enzymes in the mitochondria and releases energy in the form of ATP (adenosine triphosphate), which is the main energy currency of cells.
So, in both photosynthesis and cellular respiration, energy is either stored or released in the form of chemical bonds.
