Meaning and Definition
A property in biochemistry and molecular biology where the binding of one ligand (e.g., an oxygen molecule) to a multi-subunit protein (like haemoglobin) increases the affinity of the remaining subunits for further ligands.
More broadly, any phenomenon in complex systems where the action or property of one component positively influences the action or property of other components, leading to a synergistic, non-linear effect. It is a principle found in enzymology, receptor binding, and protein-protein interactions.
Dialectal Variation
British vs American Usage
Differences
No significant orthographic differences. Potential minor differences in domain-specific phrasing.
Connotations
Identical scientific connotations. The term carries the same precise technical meaning in both varieties.
Frequency
Equally rare in general language. Its frequency is confined to scientific literature in both regions.

FAQ
Frequently Asked Questions
No. In everyday language, 'cooperation' is a general social concept. In science, 'cooperativity' is a precise technical term describing specific non-linear interactions in molecular binding.
Yes. 'Negative cooperativity' occurs when the binding of one ligand makes it harder for subsequent ligands to bind. Both positive and negative cooperativity are important regulatory mechanisms.
Primarily in biochemistry, molecular biology, enzymology, pharmacology, and biophysics.
A sigmoidal (S-shaped) curve on a graph plotting substrate concentration against binding saturation or reaction rate, as opposed to a simple hyperbolic curve.
A property in biochemistry and molecular biology where the binding of one ligand (e.
