adenosine triphosphate

(noun)

Adenosine-5'-triphosphate (ATP) is a multifunctional nucleoside triphosphate used in cells as a coenzyme. It is often called the "molecular unit of currency" of intracellular energy transfer.

Examples of adenosine triphosphate in the following topics:

  • F10 ATP Synthase

    • ATP synthase is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate.
    • ATP synthase is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP).
    • It is formed from adenosine diphosphate (ADP) and inorganic phosphate (Pi), and needs energy.

  • The Entner–Doudoroff Pathway

    • The free energy released in this process is used to form the high-energy compounds ATP (adenosine triphosphate) and NADH (reduced nicotinamide adenine dinucleotide).

  • Shared Features of Archaea and Eukaryotes

    • The energy released generates adenosine triphosphate (ATP) through chemiosmosis, in the same basic process that happens in the mitochondrion of eukaryotic cells.

  • Fermentation Without Substrate-Level Phosphorylation

    • Fermentation is important in anaerobic conditions when there is no oxidative phosphorylation to maintain the production of ATP (adenosine triphosphate) by glycolysis.

  • Acetyl CoA and the Citric Acid Cycle

    • In addition, one complete turn of the cycle converts three equivalents of nicotinamide adenine dinucleotide (NAD+) into three equivalents of reduced NAD+ (NADH), one equivalent of ubiquinone (Q) into one equivalent of reduced ubiquinone (QH2), and one equivalent each of guanosine diphosphate (GDP) and inorganic phosphate (Pi) into one equivalent of guanosine triphosphate (GTP).
    • The NADH and QH2 that is generated by the citric acid cycle is used by the oxidative phosphorylation pathway to generate energy-rich adenosine triphosphate (ATP).

  • Energy Conservation and Autotrophy in Archaea

    • The energy released generates adenosine triphosphate (ATP) through chemiosmosis in the same basic process that happens in the mitochondrion of eukaryotic cells.

  • ABC Transporters

    • ABC transporters are transmembrane proteins that utilize the energy of adenosine triphosphate (ATP) hydrolysis to carry out certain biological processes including translocation of various substrates across membranes and non-transport-related processes such as translation of RNA and DNA repair.

  • Nitrogen Fixation Mechanism

    • Legend:I: component I (dinitrogenase; MoFe protein); II: component II (dinitrogen reductase; Fe protein); ATP: adenosine triphosphate; ADP: adenosine diphosphate; Fdx: ferredoxin; Fld: flavodoxin.

  • Two-Component Regulatory Systems

    • Signal transduction occurs through the transfer of phosphoryl groups from adenosine triphosphate (ATP) to a specific histidine residue in the histidine kinases (HK).

  • Prokaryotic Transcription and Translation Are Coupled

    • Most transcripts originate using adenosine-5'-triphosphate (ATP) and, to a lesser extent, guanosine-5'-triphosphate (GTP) (purine nucleoside triphosphates) at the +1 site.
    • Uridine-5'-triphosphate (UTP) and cytidine-5'-triphosphate (CTP) (pyrimidine nucleoside triphosphates) are disfavoured at the initiation site.
