Mercaptoethanol is the chemical compound with the formula HOCH2CH2SH. ME , as it is commonly abbreviated, is used to reduce disulfide bonds and can act as a biological antioxidant by scavenging hydroxyl radicals (amongst others). It is widely used because the hydroxyl group confers solubility in water and lowers the volatility. Due to its diminished vapor pressure, its odor, while unpleasant, is less objectionable than related thiols.
Without further context I would assume the answer here is: Hydroxyl groups.
Answer:
because the plants are more thanare autotrophs, or organisms that produce their own food. ... They are at the bottom of the food chain because they are eaten by other organisms, and they don't need to eat for energy. Producers make their own food through the process of photosynthesis instead of eating organic matte
The correct answer is the last statement.
If the regulatory serine is mutated to alanine, then acetyl-CoA carboxylase will get activated spontaneously and will produce malonyl-CoA. The increased concentrations of malonyl-CoA will obstruct the oxidation of fatty acids by preventing the entry of fatty acids into the mitochondria.
It is because the AMP-activated protein kinase phosphorylates the serine residues of acetyl-CoA carboxylase to inactivate it. If a mutation occurs in such residues, then the AMPL cannot phosphorylate acetyl-CoA carboxylase and this enzyme will get activated spontaneously.
In such a situation, there will be more than sufficient production of malonyl-CoA, which will inhibit the admittance of more fatty acid getting inside the mitochondria; this will indirectly prevent the oxidation of fatty acids.
Cyanobacteria were important for Earth's early atmosphere because they produce oxygen.
<u>Explanation</u>:
Cyanobacteria is a Phylum consists of the free living bacteria and endosymbiosis. Cyanobacteria is also called blue green algae which obtain energy through oxygenic photosynthesis and releases Oxygen gas in the atmosphere. Cyanobacteria is responsible for the early oxygen production in environment which changed the early reducing atmosphere of the earth into the oxidizing atmosphere that causes the event of great oxygenation that is rusting of the earth. During this period most of the anaerobes extinct or evolve to live as a parasite or symbol on in other hosts.
