How are photosynthesis and cellular respiration related?
Photosynthesis uses the energy from the sun by converting carbon dioxide and water into glucose and oxygen. On the other hand, cellular respiration is the process in which glucose and oxygen are converted into energy.
Therefore, these two processes are related to each other in terms of their reactants and products. The products of photosynthesis, which are glucose and oxygen, are the raw materials used during cellular respiration. On the other hand, the waste products of cellular respiration, which are carbon dioxide and water, are the raw materials used in photosynthesis.
Photosynthesis and cellular respiration are two separate biochemical processes. Photosynthesis needs the byproducts of respiration, while respiration requires the byproducts of photosynthesis. These reactions allow cells to generate and store energy while also helping to control carbon dioxide levels in the atmosphere.
Photosynthesis generates oxygen and glucose from carbon dioxide and water. Cellular respiration breaks down oxygen and glucose into water and carbon dioxide, with the by-product of ATP as energy.
The photosynthesis reaction takes place in the chloroplasts of plant cells and is an oxidation-reduction process, the addition and subtraction of electrons, which supplies power to drive the mechanism. Photosynthesis occurs in two phases. The first step is light-dependent, where sunlight and water are split into ATP and NADPH energy sources; additionally, oxygen is created. Following this is the dark reactions (also known as the Calvin cycle), where carbon dioxide and energy from the light reactions are transformed into glucose.
