Chemosynthesis In Bacteria

Chemosynthesis In Bacteria-32
Chemosynthesis is the process by which certain microbes create energy by mediating chemical reactions.So the animals that live around hydrothermal vents make their living from the chemicals coming out of the seafloor in the vent fluids!Photosynthesis makes use of solar energy, while chemosynthesis makes use of chemical energy.

Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent.

During chemosynthesis, bacteria living on the sea floor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in sea water).

In chemosynthesis the energy in the form of food is derived from chemical substances while in photosynthesis sunlight is main source of energy to prepare food. In eukaryotic photosynthesis H2O is utilized while photosynthetic bacteria utilize H2S. Some are autotrophic while others are heterotrophic.

Eukaryotes liberate oxygen while bacteria liberate sulphur. Most autotrophic bacteria can synthesize their food from substances like hydrogen sulphide.

Pure sulfur and sulfur compounds are produced as by-products.

In the diagram mussels and tubeworms are using the hydrogen sulfide released from a hydrothermal vent.Chemosynthesis is the process by which certain bacteria convert carbon dioxide and water into carbohydrates using inorganic compounds for energy.Photosynthesis uses carbon dioxide, water and light to make oxygen and glucose. Some autotrophic bacteria that exist in dark regions of the earth and ocean obtain energy from a process called chemosynthesis rather than photosynthesis.Photosynthesis takes place on land and in shallow water where sunlight can reach seaweeds.Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight.Photosynthesis is the process by which plants use the sun’s energy to make sugar (glucose) for food.Plants absorb energy from sunlight, take in carbon dioxide from the air through their leaves, take up water through their roots, and produce glucose and oxygen.Most life on Earth is dependent upon photosynthesis, the process by which plants make energy from sunlight.However, at hydrothermal vents in the deep ocean a unique ecosystem has evolved in the absence of sunlight, and its source of energy is completely different: chemosynthesis.These include decomposing bacteria, or other groups of bacteria that may be symbiotic of parasitic in nature.They oxidize inorganic compounds as a source of energy.
