Vakuoliin

Vakuoliin is a Finnish form used in scientific writing to denote movement into a vacuole or vacuoles. It is the illative case of the noun vakuoli (vacuole). In practice, vakuoliin occurs after verbs of movement, for example: aineet siirrettiin vakuoliin (the substances were transported into vacuoles). The corresponding genitive form is vakuolien, and the plural illative is vakuoleihin.

In cell biology, a vacuole is a membrane-bound organelle found in many organisms. Plant and fungal cells often have large central vacuoles that store water, ions, and metabolites and help maintain turgor pressure. Other cells contain smaller vacuoles that participate in storage, sequestration of compounds, and degradation. Vacuolar membranes contain transporters and enzymes that regulate pH, osmolarity, and digestion.

Processes that move material into vacuoles include endocytosis and vesicular trafficking, as well as autophagic pathways that deliver cytoplasmic cargo to vacuoles for breakdown. The term vakuoliin, therefore, sits at the intersection of Finnish grammar and cellular biology, and is typically found in specialized literature rather than everyday language.
