By turning inorganic molecules into organic molecules, the processes of chemosynthesis turn nonliving matter into living matter.
However, iron bacteria are not the only organisms that use metal ions as an energy source for chemosynthesis.
Other types of bacteria use arsenic, manganese, or even uranium as sources of electrons for their electron transport chains!
Because chemosynthesis alone is less efficient than photosynthesis or cellular respiration, it cannot be used to power complex multicellular organisms.
A few multicellular organisms live in symbiotic relationships with chemosynthetic bacteria, making them a partial energy source.
However, all equations for chemosynthesis typically include: Reactants: This equation is sometimes reduced to its simplest possible ratio of ingredients.
This shows the relative proportions of each ingredient necessary for the reaction, although it does not capture the full quantity of hydrogen sulfide and carbon dioxide necessary to create a single sugar molecule.The inorganic “energy source” is usually a molecule that has electrons to spare, such as hydrogen gas, hydrogen sulfide, ammonia, or ferrous iron.Like photosynthesis and cellular respiration, chemosynthesis uses an electron transport chain to synthesize ATP.Nitrogen bacteria can usually be divided into three classes:1.Nitrifying bacteria: Nitrifying bacteria grow in soils that contain ammonia.Nitrates are essential for many ecosystems because most plants need them to produce essential amino acids.Nitrification is often a two-step process: one bacteria will convert ammonia into a nitrite, and then another bacteria species will convert that nitrite into a nitrate.The term “chemosynthesis” comes from the root words “chemo” for “chemical” and “synthesis” for “to make.” Its function is similar to that of photosynthesis, which also turns inorganic matter into organic matter – but uses the energy of sunlight, instead of chemical energy to do so.Today chemosynthesis is used by microbes such as bacteria and archaea.The reduced version looks like this: Chemosynthesis allows organisms to live without using the energy of sunlight or relying on other organisms for food.Like chemosynthesis, it allows living things to make more of themselves.
