Sulfur is one of the constituents of many proteins, vitamins and hormones. It recycles as in other biogeochemical cycles.
The essential steps of the sulfur cycle are:
- Mineralization of organic sulfur to the inorganic form, hydrogen sulfide: (H2S).
- Oxidation of sulfide and elemental sulfur (S) and related compounds to sulfate (SO42-).
- Reduction of sulfate to sulfide.
- Microbial immobilization of the sulfur compounds and subsequent incorporation into the organic form of sulfur.
These are often termed as follows: Assimilative sulfate reduction (see also sulfur assimilation) in which sulfate (SO42-) is reduced to organic sulfhydryl (otherwise known as thiol) groups (R-SH) by plants, fungi and various prokaryotes. The oxidation states of sulfur are +6 in sulfate and -2 in R-SH. Desulfuration in which organic molecules containing sulfur can be desulfurated, producing hydrogen sulfide gas (H2S), oxidation state = -2. Note the similarity to deamination. Oxidation of hydrogen sulfide produces elemental sulfur (So), oxidation state = 0. This reaction is done by the photosynthetic green and purple sulfur bacteria and some chemolithotrophs. Further oxidation of elemental sulfur by sulfur oxidizers produces sulfate. Dissimilative sulfur reduction in which elemental sulfur can be reduced to hydrogen sulfide. Dissimilative sulfate reduction in which sulfate reducers generate hydrogen sulfide from sulfate.
Human impact on the sulfur cycle is primarily in the production of sulfur dioxide (SO2) from industry (e.g. burning coal) and the internal combustion engine. Sulfur dioxide can precipitate onto surfaces where it can be oxidized to sulfate in the soil (it is also toxic to some plants), reduced to sulfide in the atmosphere, or oxidized to sulfate in the atmosphere as sulfuric acid, a principal component of acid rain

What part of the sulfur cycle is the slowest or fastest?
The parts of the cycle in the ground like plants and oxinization are slowest, while the parts in the sky and air go the fastest.
What is sulfur Oxides?
Sulfur oxides are the oxides of sulfur with oxygen in -2 oxidation state. There are two main oxides of sulfur. They are sulfur dioxide (SO2) and sulfur trioxide (SO3).
What is the covalent compound name for CF4?
This compound is tetrafluoromethane.
What is the number of moles of sulfur in sulfur trioxide?
There is 1 molecule of sulfur in sulfur trioxide so there is 1 mole of sulfur in 1 mole of sulfur trioxide
What is 2.50 mol of sulfur?
1 mol Sulfur is 32 g Sulfur So 2.5 mol Sulfur is 80 g Sulfur
What is the importance of sulfur cycle?
The sulfur cycle is the collection of processes by which sulfur moves to and from minerals (including the waterways) and living systems.
What is one of the main differences between the phosphorus and sulfur cycles?
The atmosphere has no significant role in the phosphorus cycle, but is an essential part of the sulfur cycle.
Why is sulfur cycle important to the environment?
ewan
What is bacterias role in the sulfur cycle?

What are the nature cycles?
nitrogen cycle, carbon cycle, water cycle, and sulfur cycle
What is the importance of cycling?
The sulfur cycle is the collection of processes by which sulfur moves to and from minerals (including the waterways) and living systems.
What happen the animal if lack of sulfur?
it is important because it is a cycle the need to live
Interaction between non living things in the environment?
they interact in the way of nitrogen cycle, phosphorus cycle ,sulfur cycle and ect . . ....
What part of the sulfur cycle is the slowest or fastest?
The parts of the cycle in the ground like plants and oxinization are slowest, while the parts in the sky and air go the fastest.
What are the different cycles in nature?
A payroll cycle is the determined period of time of allocated hours worked.
In what cycle does molecules pass around again within the biosphere?
The carbon cycle The nitrogen cycle The Phosphorus cycle The Sulfur cycle The water cycle The Calcium cycle There could also be a Hydrogen and Oxygen cycle but these are usually included in the Carbon, Water and Nitrogen cycle. There could also be a rare mineral cycle too but this seems to simplistic to be honoured with a name.
How does nitrogen cycle through ecosystem?
The major elements cycled in nature are carbon, nitrogen, phosphorus, and sulfur, and oxygen which forms part of all the cycles.
