Explanation:

typical representative of high-energy' compound with phosphoanhydride bond (diphos- phate bond) is ATP (adenosine triphosphate). In this compound are two high-energy' diphosphate bonds (phosphoanhydride bonds). The third phosphate bond between phosphate and ribose is not enery-rich, it is phosphate ester bond.

Answer 2

In short

Energy can be stored in the chemical bonds within molecules in the cell, but not all chemical bonds are equally energetic. When broken, some bonds will release more energy than others. A phosphate is a phosphorus atom bonded to three oxygen atoms (PO3). When it’s bonded to another molecule, the bond between them is called a phosphate bond. Breaking the phosphate bond releases a lot of energy.

For example, when one molecule of glucose is broken down by the cell for fuel, it releases way too much energy to be used all at once (around 2,800 kilojoules [kJ]), so the formation of many ATP molecules (carrying about 32 kJ each) can be used as a way to transfer this energy to be used to do work elsewhere.

In long

The chief energy-rich compound of all biological cells is adenosine triphosphate. ATP consists of adenine, ribose and three phosphoric acid molecules. ATP is energy-rich because its terminal phosphate group can be hydrolysed to release energy.

Many biochemical reactions are endergonic in nature and cannot occur spontaneously unless energy is supplied. When such a reaction is coupled with another reaction which is exergonic in nature, then only can the reactants be enzymatically driven to give the products.

Hydrolysis of ATP is the most common exergonic reaction coupled to drive an endergonic biochemical reaction. When ATP is hydrolysed, the quantity of energy set free (∆G) varies depending on pH, concentrations of Mg++ and ADP etc. Under standard conditions (∆G°) the free-energy of ATP hydrolysis ATP –> ADP + Pi is taken to be -7.3 K cal/mole of ATP.

Besides ATP, other energy-rich compounds in biological cells are also present, such as guanosine triphosphate, uridine triphosphate, cytidine triphosphate, phosphoenol pyruvate, acetyl phosphate etc.

Breaking the phosphate bond releases a lot of energy.

Molecules containing high-energy bonds are themselves energy-rich compounds. These energy-rich compounds are the cell’s currency — they can be used to power energy-consuming biochemical reactions.

Another important group of energy-rich molecules are those derived from coenzyme A. One example of these is acetyl-CoA, which has an energy-rich sulfur-containing thioester bond instead of phosphate bonds. The energy released from the breakdown of acetyl-CoA is just enough to make a phosphate bond in ATP.

Although used for all types of metabolism, these molecules are essential for microbes that rely on a type of anaerobic metabolism called fermentation, where food is broken down in the absence of oxygen.

Both ATP and acetyl-CoA are short-term storage molecules — they’re usually used to power other reactions relatively quickly. For longer-term energy storage, microbes put their energy reserves elsewhere
