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.
