How Does Archaebacteria Obtain Energy; There are many different types of energy sources used by Archaea in their metabolism. These processes are classified nutritionally depending on the energy and carbon sources that they use. Inorganic compounds such as sulfide or ammonia are sources of energy for certain archaea, known as lithotrophs.

There are also instances of nitrifiers, methanogens, and methane oxidizers. When one substance transfers electrons to another, energy is released, allowing the cell to function properly. The donor molecule accepts electrons, whereas the acceptor molecule donates electrons. Chemiosmosis, the same underlying mechanism that happens in the mitochondrion of eukaryotic cells, is used to convert the liberated energy into adenosine triphosphate (ATP).

They represent the known highest temperature limit of life because they can survive at such high temperatures. Hydrothermal fields and vents in the marine environment have been found to include hyperthermophilic archaebacteria (see Stetter, 1982, 1986; Neuner et al., 1990).

There are two distinct groups of sulfur-dependent archaebacteria: the aerobic sulfur-oxidizing Sulfolobales and the strictly anaerobic sulfur-reducing Thermoproteales (see Brock et al., 1972; Brierley and Brierley, 1973; Zillig et al., 1980; Woese et al., 1984). (see Brock et al., 1984). (1981, 1982, 1983, Zillig et al. High-temperature habitats are dominated by archaebacteria, which are both primary producers and consumers of organic matter. At this point, their distribution and possible methods of spread are mostly unknown.

When you look at bacteria, you see that they have cell walls and flagella, like other bacteria. Some archaea are lithotrophs, which means they get their energy from inorganic materials like sulfur. These archaea made ATP by using electron transport chains to make it. Other types of archaea are phototrophs, which get their energy from the sun.

Archaebacteria can also be found in the same places. In the past, Archaea lived in places like caves and on the ground. Archaea are bacteria that help set the limits of what can live on Earth. They were first found and characterized in places that were hard to get to, like hydrothermal vents and hot springs on the ground. In addition, they were found in a lot of places that were very salty, acidic, and without any air.

In this case, how do archaebacteria get food?

Bacteria aren’t the only organisms that get their food this way. People who make their own food don’t use photosynthesis, which is when carbon dioxide, water, and the sun’s energy are turned into food. Instead, they use a different process. From different types of carbon found in the environment, they may get their energy instead of light.


They were shocked to find one-celled creatures in the samples. Archaebacteria is the kingdom in which these organisms belong.

When it comes to classifying archaea and other types of prokaryotes, the debate is always going on. Archaea are now divided into groups based on structural similarities and shared ancestors. In these classifications, the sequences of ribosomal RNA genes are very important. This helps us understand how species are related (molecular phylogenetics). Euryarchaeota and Crenarchaeota are the two main groups of archaea species that can be grown and studied.

Other groups have been suggested, like the strange species Nanoarchaeum, which was found in 2003 and given its own phylum, the Nanoarchaeota. Besides that, a new phylum, Korarchaeota, has been proposed. It is made up of a small number of unique thermophilic species that show traits from both major phyla, but they are most closely linked to the Crenarchaeota. The Archaeal Richmond Mine acidophilic nano organisms (ARMAN), which include Micrarchaeota and Parvarchaeota, were found in 2006 and are some of the smallest organisms known. They are not related to any of these families.

The Thaumarchaeota, Aigarchaeota, Crenarchaeota, and Korarchaeota superphylum were thought to be important to the emergence of eukaryotes in 2011 when they were first thought of. In 2017, it was thought that the newly found and renamed Asgard superphylum is closer to the first eukaryote and is a sister group to TACK.

Two different types

Archaea and Bacteria have some things in common, but they are also two different types of living things: they are not the same thing.

Archaea and Bacteria both have one cell. This makes them different from eukaryotes, which include both single-celled and multi-celled organisms.
Archaea and bacteria don’t have organelles or other membrane-bound structures inside their cells, so they don’t have cells. The result is that archaea and bacteria don’t have a nucleus like eukaryotes. This means that their genetic material doesn’t get mixed up with the rest of the cell.
It’s the same thing for Archaea and Bacteria. Both have a single, circular chromosome, which is a circular piece of double-stranded DNA in the nucleoid area of the cell. In contrast, a lot of eukaryotes have a lot of linear chromosomes.
Archaea and Bacteria make new cells by “fission,” which is when a single cell makes copies of its chromosome and splits in two. Eukaryotes grow through mitosis, which requires more steps to make sure that many chromosomes are copied and divided between two daughter cells. Many eukaryotes can reproduce sexually through a process called meiosis. In this process, the number of chromosomes is halved to make haploid cells (also called sperm or eggs), and two haploid cells join together to make a new creature. Archaea and bacteria can’t have babies through sex.

Archaebacteria that grow at exceptionally high temperatures have been discovered in hot springs and hot seafloors. It was discovered by Fischer et al. (1983) that some extremely thermophilic archaebacteria may exist only on carbon dioxide, obtaining their energy from hydrogen oxidation by sulfur to create hydrogen sulfide (H2S) (H2S). The outcome is a new type of anaerobic metabolism, a possible primal mode of life, that they are capable of.

An anaerobic environment is one where there is not enough oxygen for them to thrive. They produce energy by converting water and CO2 into methane, which is then converted into ATP. Both anaerobic respiration and bacteriorhodopsin, a pigment that converts light into energy, provide them with the energy they need.

In the same way, no one knows how archaea get power.
Cell walls and flagella are found in archaebacteria, just as they are in other bacteria. Lithotropic archaea get their energy from inorganic sources like sulfide. The electron transport chains of these archaea were employed to synthesize ATP. Other archaea are phototrophs, dependent on the sun’s rays to obtain their energy.

What other places may archaebacteria be found other than the ones listed above? Archaeal ecosystems This microbe, called Archaea, defines the boundaries of life on our planet. Hydrothermal vents and terrestrial hot springs have yielded a wealth of information on these organisms. It has been found in a variety of highly salinized, acidic, and anaerobic conditions.

How else do archaebacteria get their food?

There are many people that eat like bacteria. Archaeans don’t use photosynthesis, the process of turning CO2, water, and solar energy into food. It’s possible that instead of relying on light, they’ll employ carbon sources that can be found in the environment, along with chemicals.

Archaebacteria have an estimated cell count of ten to one hundred billion.

Discovering unicellular creatures in the samples surprised them. Archaebacteria is the current name given to this group of microorganisms.

In contrast, autotrophic archaea use atmospheric CO2 as a carbon source through a process known as carbon fixation. A novel metabolic pathway known as the 3-hydroxypropionate/4-hydroxybutyrate cycle is used in this process. This is a highly modified variant of the Calvin cycle. The Euryarchaeota, on the other hand, use the reductive acetyl-CoA route, whereas the Crenarchaeota use the reverse Krebs cycle. Carbon fixation is powered by inorganic energy.
