adenosine triphosphate

A student studies a diagram of adenosine triphosphate in a biology textbook.

Definition
  1. Noun:
    • A nucleotide derived from adenosine that occurs in muscle tissue; the major source of energy for cellular reactions: Adenosine triphosphate (ATP) is a complex organic chemical that provides energy to drive many processes in living cells.
Usage Examples
  • Noun:
    • Muscle contraction requires adenosine triphosphate.
    • The mitochondria are responsible for producing adenosine triphosphate.
    • Adenosine triphosphate is often described as the "molecular unit of currency" of intracellular energy transfer.
Advanced Usage
  • "ATP hydrolysis": The chemical reaction where adenosine triphosphate is broken down into adenosine diphosphate (ADP) and an inorganic phosphate, releasing energy.
    • The energy released during ATP hydrolysis powers cellular work.
  • "ATP synthase": The enzyme that creates adenosine triphosphate.
    • ATP synthase is a key component of the cellular machinery for generating adenosine triphosphate.
Variants and Related Words
  • ATP (n): The common abbreviation for adenosine triphosphate.
    • Cells constantly recycle ATP.
  • Adenosine diphosphate (ADP) (n): A nucleotide formed when adenosine triphosphate loses one phosphate group.
  • Adenosine monophosphate (AMP) (n): A nucleotide formed from adenosine and one phosphate group.
Synonyms
  • Energy currency: A metaphorical term for adenosine triphosphate, emphasizing its role in storing and transferring chemical energy within cells.
  • High-energy phosphate compound: A biochemical term describing molecules like adenosine triphosphate that store energy in phosphate bonds.
Related Phrases and Concepts
  • ATP-ADP cycle: The continuous process of adenosine triphosphate being converted to ADP (releasing energy) and then being regenerated (requiring energy input).
    • The ATP-ADP cycle is fundamental to metabolism.
  • Phosphorylation: The biochemical process of adding a phosphate group to a molecule, often using a phosphate from adenosine triphosphate.
    • The phosphorylation of glucose is the first step in glycolysis.
