Main Differences between Photosynthesis and Respiration in table form Photosynthesis and respiration are two fundamental processes that sustain life on Earth. While they may seem like opposing forces, they are interconnected in the circle of life. In this blog post, we’ll delve into the main differences between photosynthesis and respiration, highlighting their distinct roles in the biosphere.
What is Photosynthesis
Photosynthesis according to National Geographic, is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What is Respiration
Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP (the currency of energy in cells). From prokaryotic bacteria and archaeans to eukaryotic protists, fungi, plants, and animals, all living organisms undergo respiration.
Main Differences between Photosynthesis and Respiration in table form
Below is the main differences between Photosynthesis and Respiration in table form
| Basis of Comparison | Photosynthesis | Respiration |
| Meaning | It is the process in which green plants and few bacteria use sunlight and water to convert it into energy. | It refers to the process in which all living organisms except plants convert energy and offer to the different cells of the body. |
| Occurrence | Occurs in plants containing chlorophyll and some bacteria | Occurs in all living organisms |
| By-Products | Glucose, oxygen, and water | Carbon dioxide, water, and energy (ATP) |
| Process | It takes place in chloroplasts | It takes place in mitochondria |
| Undergoes | Anabolic process | Catabolic process |
| Reactants | Carbon dioxide, water, and light energy | Glucose and oxygen |
| Reaction | Endothermic reaction because it needs energy | Exergonic reaction because it releases energy |
| Function | Produces food and captures the energy | Takes in oxygen and liberates out carbon dioxide |
| Sunlight | Requires sunlight because it is mandatory | Does not require sunlight as it takes place all the time |
| CO2 and water | Absorbs carbon dioxide and water | Releases carbon dioxide and water |
| Chemical reaction | 6CO2 + 6H2O → C6H12O6 + 6O2 | C6H12O6 + 6O2 → 6CO2 + 6H2O |
Why are photosynthesis and respiration important
Why are photosynthesis and respiration important? Well, respiration and photosynthesis are the critical parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
What are the 6 steps of the carbon cycle
There are six main processes in the carbon cycle:
- photosynthesis,
- respiration,
- exchange,
- sedimentation,
- extraction,
- and combustion.
