Cellular Respiration and Photosynthesis

Every breath you take, and every bite you eat connects to two vital processes: photosynthesis and cellular respiration.

These processes form a continuous cycle that powers life on Earth.

Cellular respiration is the reverse of photosynthesis. During photosynthesis, sunlight, water, and carbon dioxide produce glucose as an energy source and oxygen as a byproduct.

Meanwhile, in cellular respiration, the breakdown of glucose in the presence of oxygen releases energy in the form of ATP. This process also produces carbon dioxide and water as byproducts.

So here, the equation for cellular respiration is the reverse of photosynthesis, creating a seamless exchange of gases.

The oxygen plants release during photosynthesis is used by plants and animals for cellular respiration. In return, the carbon dioxide released during cellular respiration is used by plants to photosynthesize.

This exchange also makes photosynthesis and cellular respiration key contributors to the carbon cycle, where carbon dioxide released into the environment is reabsorbed during photosynthesis. Together, these processes recycle energy and maintain balance in life on Earth.
