adenosine triphosphatase
Very LowTechnical/Scientific
Definition
Meaning
An enzyme that catalyzes the hydrolysis of adenosine triphosphate (ATP) into adenosine diphosphate (ADP) and a free phosphate ion, releasing energy for cellular processes.
A class of enzymes (often abbreviated as ATPase) essential for energy transfer in biological systems, involved in processes like muscle contraction, nerve impulse propagation, and active transport across cell membranes.
Linguistics
Semantic Notes
The term is almost exclusively used in biochemistry, molecular biology, and related life sciences. It refers to a functional class of enzymes rather than a single specific protein.
Dialectal Variation
British vs American Usage
Differences
No significant lexical or spelling differences. Pronunciation may vary slightly (see IPA).
Connotations
Identical technical connotations in both varieties.
Frequency
Equally rare outside specialized scientific contexts in both regions.

Examples
By Part of Speech
verb
British English
- The protein is believed to adenosine triphosphatase under specific conditions.
- Does this complex actually adenosine triphosphatase?
American English
- The complex may adenosine triphosphatase in the presence of magnesium.
- We need to test if it can adenosine triphosphatase efficiently.
adverb
British English
- The reaction proceeded adenosine triphosphatase-ly (highly contrived).
- It functioned adenosine triphosphatase-like (contrived).
American English
- It acted adenosine triphosphatase-wise (contrived).
- The mechanism worked in an adenosine triphosphatase manner (contrived).
adjective
British English
- The adenosine triphosphatase function was impaired.
- We observed adenosine triphosphatase activity in the sample.
American English
- The adenosine triphosphatase assay yielded clear results.
- This is a key adenosine triphosphatase protein.
Examples
By CEFR Level
- This word is for scientists.
- Adenosine triphosphatase is an important enzyme in biology.

Mnemonic
Think: ADenosine TRIphosphate-ASE. It's the ASE (enzyme) that works on ATP (adenosine TRIphosphate).
Conceptual Metaphor
A molecular battery discharger.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'triphosphatase' as three separate words ('три фосфатаза'). It is a single compound term.
- Do not confuse with 'аденозинтрифосфат' (ATP, the substrate) – this is the enzyme that acts on it.
Common Mistakes
- Misspelling as 'adenosine triphospatase' (missing 'h').
- Using it interchangeably with 'ATP' (the molecule, not the enzyme).
- Incorrect plural: 'adenosine triphosphatases' is correct for multiple types.

FAQ
Frequently Asked Questions
No. ATP (adenosine triphosphate) is the energy-carrying molecule. Adenosine triphosphatase (ATPase) is the enzyme that breaks it down.
It is found throughout the body in cell membranes (e.g., ion pumps), mitochondria, muscle fibers (myosin), and other cellular structures.
It is crucial for releasing the chemical energy stored in ATP, which powers virtually every energy-requiring process in a cell.
The sodium-potassium pump (Na+/K+-ATPase) in nerve cells is a well-known example, essential for nerve impulses.
