In this article, we discuss the Difference Between Photosynthesis and Respiration of Class 10 Science Chapter One, Life Processes with a detailed explanation.
Photosynthesis: It is a build-up or anabolic process that forms organic from inorganic materials which the help of light energy. It is, therefore, an endergonic process
6CO₂ +6H₂O + 686kcal ⟶ C₆H₁₂O₆ + 6O₂
Respiration: It is a breakdown or catabolic process in which a respiratory substrate is broken down oxidatively to release energy. It is, therefore an exergonic Process
C₆H₁₂O₆ + 6O₂ ⟶ 6CO₂ +6H₂O + 686kcal
Difference Between Photosynthesis and Respiration
| Photosynthesis | Respiration | |
|---|---|---|
| 1 | Metabolism: Photosynthesis is a synthetic or anabolic process | Respiration is a breakdown or catabolic process |
| 2 | Energy Relation: It is an endergonic process | It is an exergonic process |
| 3 | Energy Conversion: It converts light energy into energy | It liberates chemicals energy which is used as such or changed into other forms of energy |
| 4 | Timing: Photosynthesis occurs during the daytime when light is available | Respiration occurs all the time |
| 5 | Cells: It occurs only in green cells | It occurs in all types of living cells |
| 6 | Carbon Dioxide: It absorbs carbon dioxide | Respiration liberates carbon dioxide |
| 7 | Oxygen: Photosynthesis liberates oxygen | Respiration consumes oxygen |
| 5 | Raw Materials: They are carbon dioxide and water | They are glucose and oxygen |
| 6 | End Products: They are glucose, the organic substances and oxygen | End products are carbon dioxide and water |
| 7 | Weight: There is net gain of weight | There is net loss of weight |
