A study suggests much of the water originated in rocks from which Earth is built. AUDIE CORNISH, HOST: ... She says that source of water could have been farther out in the solar system, like maybe icy comets or water-rich asteroids that hit the newly formed Earth and watered it. This has long been the prevailing view
Answer & explanation:
Adenosine triphosphate (ATP) is a molecule made up of <u>one adenosine molecule</u> and <u>three phosphate radicals</u> (P) capable of storing small amounts of energy (from the breakdown of food) in their chemical bonds, acting as a temporary energy container.
ATP is directly linked to cell metabolic processes such as cellular respiration and photosynthesis. When cells need energy, for the sodium-potassium pump, for example, the ATP molecule breaks down.
This breakdown is made by hydrolysis (ATP breaks using water), so the bond between the phosphate group 2 and the phosphate group 3 breaks down, leaving one Adenosine diphosphate (ADP) molecule, which has two phosphate radicals.
At the end of the process the energy that kept the phosphate groups bound is released and used in processes such as <u>stretching and shortening of muscle fibers</u>, nerve impulses and hormonal regulation. These processes utilize the active energy released by ATP hydrolysis.
ATP - ADP conversion is the fundamental way to get energy because the cell cannot use the glucose molecule directly.
Answer:
Phosphates are critical part of life because of the diverse roles they perform in the lives of living organisms, especially in DNA and RNA molecules.
Phosphates are formed from two elements, phosphorus and oxygen. Phosphorus is a very important element that play a crucial roles in the formation of bones and teeth. It is also plays vital roles in carbohydrate metabolism, fat metabolism, protein synthesis and repair of worn out tissues. Oxygen on the other hand is required for oxidation of biological fuel and for breathing.
Phosphates are usually formed from one atom of phosphorus and four atoms of oxygen, it has the chemical formula PO4. Phosphate is an important component of DNA and RNA molecules, phosphates hold these molecules together. Phosphate molecule is also found in ATP, which is the energy currency of living cells.
