Blog 6 Photosynthesis compared to Cellular Respiration

The formula for photosynthesis and cellular respiration is shown below. The formula basicly explains what what happens in the process.
Photosynthesis:
6CO₂(6 carbon dioxide molecules) + 6H₂O(6 water chemicals + energy
--> 6O₂(6 oxygen) + C₆H₁₂O₆(sugar)

Cellular Respiration (the reverse reaction):
6O₂(6 oxygen) + C₆H₁₂O₆(sugar)
--> 6H₂O(6 water) + 6CO₂(6 carbon dioxide) + energy

Photosynthesis ProcessPhotosynthesis is a chemical process that takes place in the presence of sunlight, where in plants make their food and build stores of energy. This occurs in chlorophyll containing plant cells. Chlorophyll is a pigment found in plant leaves that gives plants their green color. Chlorophyll absorbs the light energy and utilizes it to produce carbohydrates (sugars) from carbon dioxide (CO₂) and water (H₂O). This chemical reaction produces oxygen which is released into the atmosphere.

Cellular RespirationCellular respiration is the process of oxidizing food molecules or breaking down chemical bonds of glucose into carbon dioxide and water. The energy released during the process is trapped in the form of ATP (Adenosine Tri-Phosphate) and used by different energy consuming activities of the cell. In other words, it's a set of the metabolic reactions that occur in the mitochondria of the cells of organisms to convert biochemical energy from nutrients into ATP, and release byproducts. The complete breakdown of glucose into carbon dioxide and water involves two major steps: glycolysis and aerobic respiration.

Differences :
-Photosynthesis is where plants use sunlight to make food and cellular respiration uses plants or other living organism to convert food into energy.
-Photosynthesis takes place inside the chloroplasts and cellular respiration takes place inside the mitochondria.
-Photosynthesis requires energy to produce glucose and cellular respiration uses the glucose produced from photosynthesis to make energy (ATP).
-Photosynthesis takes carbon dioxide, water and sunlight from the atmosphere to create sugar and releases oxygen back into the air and cellular repiration combines sugars with oxygen, releases the energy as ATP and carbon dioxide and water as by products.
-Photosynthesis occurs in plants and some bacteria and cellular respiration occurs in all living organisms.
