adenosine triphosphate

(noun)

a multifunctional nucleoside triphosphate used in cells as a coenzyme, often called the "molecular unit of energy currency" in intracellular energy transfer

Examples of adenosine triphosphate in the following topics:

  • ATP: Adenosine Triphosphate

    • Adenosine triphosphate (ATP) is the energy currency for cellular processes.
    • Adenosine triphosphate (ATP) is comprised of the molecule adenosine bound to three phosphate groups .
    • Adenosine is a nucleoside consisting of the nitrogenous base adenine and the five-carbon sugar ribose.
    • The bond between the beta and gamma phosphate is considered "high-energy" because when the bond breaks, the products [adenosine diphosphate (ADP) and one inorganic phosphate group (Pi)] have a lower free energy than the reactants (ATP and a water molecule).
    • It has an adenosine backbone with three phosphate groups attached.

  • Mitochondria

    • Mitochondria are organelles that are responsible for making adenosine triphosphate (ATP), the cell's main energy-carrying molecule.
    • Mitochondria are often called the "powerhouses" or "energy factories" of a cell because they are responsible for making adenosine triphosphate (ATP), the cell's main energy-carrying molecule.

  • ATP in Metabolism

    • Living cells accomplish this by using the compound adenosine triphosphate (ATP) .
    • The core of ATP is a molecule of adenosine monophosphate (AMP), which is composed of an adenine molecule bonded to a ribose molecule and to a single phosphate group.
    • The addition of a second phosphate group to this core molecule results in the formation of adenosine diphosphate (ADP); the addition of a third phosphate group forms adenosine triphosphate (ATP).
    • ATP (adenosine triphosphate) has three phosphate groups that can be removed by hydrolysis to form ADP (adenosine diphosphate) or AMP (adenosine monophosphate).The negative charges on the phosphate group naturally repel each other, requiring energy to bond them together and releasing energy when these bonds are broken.

  • Covalent Bonds and Other Bonds and Interactions

    • Adenosine triphosphate, or ATP, is the most-commonly used cofactor in all of biology.
    • Adenosine Triphosphate, or ATP, is the most commonly used cofactor in nature.

  • Food Energy and ATP

    • Adenosine triphosphate, or ATP, is the primary energy currency in cells.

  • Transforming Chemical Energy

    • The energy released by cellular respiration is temporarily captured by the formation of adenosine triphosphate (ATP) within the cell.

  • Importance of Carbohydrates

    • As an immediate source of energy, glucose is broken down during the process of cellular respiration, which produces adenosine triphosphate (ATP), the energy currency of the cell.

  • The Role of Passive Transport

    • Some materials are so important to a cell that it spends some of its energy (hydrolyzing adenosine triphosphate (ATP)) to obtain these materials.

  • The Energy-Requiring Steps of Glycolysis

    • In the first half of glycolysis, two adenosine triphosphate (ATP) molecules are used in the phosphorylation of glucose, which is then split into two three-carbon molecules as described in the following steps.

  • ATP Yield
