Trees release oxygen which is a by-product of photosynthesis, and we breathe in oxygen so that our cells can carry out cellular respiration and generate ATP.
Respiration and photosynthesis are biological reactions in the environment that complement each other. Both are similar reactions that occur in a reverse manner. In the process of respiration, oxygen and glucose yield water and carbon dioxide, while carbon dioxide and water yields glucose and oxygen in photosynthesis.
Both respiration and photosynthesis function adequately as living organisms provide carbon dioxide required for plants that undergo photosynthesis and produces glucose. Bacteria and plants release oxygen that is required for all living organisms for respiration.
The equation of cellular respiration is the reverse of photosynthesis. The interchange of oxygen and carbon dioxide by cellular respiration and photosynthesis helps in maintaining both atmospheric oxygen and carbon dioxide stable.
Differences between Cellular Respiration and Photosynthesis
|Occurs in all living organisms.||Occurs only in all green plants, algae, and in some bacteria.|
|The entire process occurs in Mitochondria.||The entire process occurs in Chloroplasts.|
|Glucose and oxygen are the reactants of this process.||Carbon dioxide, water, and light energy are the reactants of this process.|
|Carbon dioxide, water, and energy (ATP) are the by-products.||Glucose, oxygen, and water are the by-products.|
|Undergoes Catabolic Process.||Undergoes Anabolic Process.|
|Oxygen is taken in and carbon dioxide is liberated out.||Producing food and capturing energy.|
|In this process, food particles are broken down to release energy.||In this process, food is synthesis by capturing the energy.|
|It is an exergonic reaction as energy is released.||It is an endothermic reaction as it requires energy.|
|This process does not require sunlight since cellular respiration occurs all the time.||This process requires sunlight since photosynthesis occurs only in the presence of sunlight.|
|The chemical reaction of cellular Respiration is
C6H12O6 + 6O2 → 6CO2 + 6H2O
|The chemical reaction of photosynthesis is
6CO2 + 6H2O → C6H12O6+ 6O2
