Photosynthesis stores energy by converting light energy into chemical energy in the form of glucose (sugar). This process happens in plants, algae, and some bacteria. It can be summarized as:
Sunlight + Water + Carbon Dioxide → Glucose + Oxygen
Respiration releases energy by breaking down glucose and releasing the stored energy as ATP (adenosine triphosphate), the main energy currency of cells. This happens in all living organisms. It can be summarized as:
Glucose + Oxygen → Carbon Dioxide + Water + Energy (ATP)
So, photosynthesis is like a charging station for energy, and respiration is like using the energy that was stored. They are complementary processes that keep life going on Earth.
