6.4: ATP: Adenosine Triphosphate
ATP is the primary energy-supplying molecule for living cells. ATP is made up of a nucleotide, a five-carbon sugar, and three phosphate groups. The bonds that connect the phosphates (phosphoanhydride bonds) have high-energy content.
Why living things use ATP as universal energy currency
ATP, adenosine triphosphate, is used by all cells as an energy intermediate. During cellular respiration, energy is captured when a phosphate is added to ADP (adenosine diphosphate) to generate ATP; cleavage of that
Adenosine triphosphate (ATP) | Definition, Structure,
adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes..
ATP in Living Systems | Biology for Majors I
ATP functions as the energy currency for cells. It allows the cell to store energy briefly and transport it within the cell to support endergonic chemical reactions. The structure of ATP is that of an RNA nucleotide with three phosphates
Metabolic Energy
Adenosine 5′-triphosphate (ATP) plays a central role in this process by acting as a store of free energy within the cell (Figure 2.31). The bonds between the phosphates in ATP are known as high-energy bonds because their hydrolysis
Metabolic Energy
Other molecules, including other nucleoside triphosphates (e.g., GTP), also have high-energy bonds and can be used as ATP is to drive energy-requiring reactions. For most reactions, however, ATP provides the free energy. The energy
Why is ATP used as a source of energy rather than glucose?
Desirable Properties for an Energy Currency. Here are some. You may be able to think of others. It can be used in a wide variety of chemical processes in the cell. It can store and release
Adenosine triphosphate (ATP) | Definition, Structure,
ATP is not a storage molecule for chemical energy; that is the job of carbohydrates, such as glycogen, and fats. When energy is needed by the cell, it is converted from storage molecules into ATP. ATP then serves as a
