ADVERTISEMENTS:
The upcoming discussion will update you about the differences between Photosynthesis and Respiration.
Difference # Photosynthesis:
1. It takes place in the presence of sunlight only.
2. A plant can live without photosynthesis for a number of days.
ADVERTISEMENTS:
3. Only green cells of the plant are capable of accomplishing photosynthesis.
4. It absorbs sunlight and is an endothermic reaction.
5. It utilizes carbon dioxide and water.
6. Photosynthesis is an anabolic process It builds up complex compounds from simple inorganic compounds.
ADVERTISEMENTS:
7. It increases the weight of the organisms.
8. It changes radiant energy into chemical energy.
9. The raw materials of photosynthesis are carbon dioxide and water.
10. The end products are carbohydrates and oxygen.
11. Gaseous exchange involves release of oxygen and absorption of carbon dioxide.
12. It produces ATP by harvesting light energy.
13. Hydrogen of water is used in the synthesis of NADPH.
ADVERTISEMENTS:
14. ATP and NADPH are employed in the synthesis of organic compounds.
Difference # Respiration:
ADVERTISEMENTS:
1. It continues throughout day and night, in sun and darkness.
2. No organism can live without respiration even for a few minutes.
3. All the cells of an organism perform respiration.
4. It gives out energy and is, therefore; exergonic.
ADVERTISEMENTS:
5. It evolves carbon dioxide and water.
6. It is a catabolic process in which complex substances are broken down into simple substances.
7. It decreases the weight of the organisms.
8. It releases the potential or chemical energy which is used variously in the body.
ADVERTISEMENTS:
9. The raw materials of respiration are sugars and oxygen.
10. The end products are carbon dioxide and water.
11. Gaseous exchange involves absorption of oxygen and evolution of carbon dioxide.
12. Respiration forms ATP from energy liberated during oxidation of food.
ADVERTISEMENTS:
13. Hydrogen of food is used in the formation of NADH, NADPH and FADH2.
14. ATP and reduced coenzymes are made available to cells for various metabolic activities.
