Key Difference Between Photosynthesis and Chemosynthesis: How Do Plants and Bacteria Get Energy?
Difference between photosynthesis and chemosynthesis
La photosynthesis and chemosynthesis They are fundamental processes in the production of energy in living beings, but they work differently.
Photosynthesis
La photosynthesis It is the process by which plants, algae and some bacteria transform the light energy of the sun in chemical energy, which is stored in glucose molecules. Photosynthesis is essential for life on Earth, since plants and algae are the basis of the chain food and produce the oxygen we breathe.
Photosynthesis takes place in the chloroplasts of plant cells. Chloroplasts contain pigments called clorofila, which absorb sunlight and use it to generate chemical energy through a series of reactions.
The general formula for photosynthesis is:
- CO2 + H2O + sunlight → glucose + O2
In this reaction, carbon dioxide (CO2) and water (H2O) combine with light energy to produce glucose and oxygen (O2).
chemosynthesis
La chemosynthesisit is a process by which some bacteria transform the chemical energy of inorganic compounds such as hydrogen sulfide (H2S) or ammonia (NH3) in organic energy, without the need for sunlight.
This process It takes place in bacteria in regions where there is no sunlight, such as on the ocean floor.
The general formula for chemosynthesis is:
- H2S + O2 + CO2 → H2SO4 + glucose
In this reaction, hydrogen sulfide (H2S), oxygen (O2), and carbon dioxide (CO2) combine to produce sulfuric acid (H2SO4) and glucose.
In short, the main difference between photosynthesis and chemosynthesis is that the former uses light energy from the sun to produce chemical energy, while the latter uses the chemical energy of inorganic compounds. Both processes are crucial for maintaining life on the planet, and their study and understanding are fundamental for biology and ecology.
