Definition of active transport in English:

active transport

noun

mass nounBiology

The movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
〔生〕主动转运，主动运输
Example sentencesExamples
- Complex processes regulate both passive and active transport across the nuclear membrane.
- Uric acid, formed from nucleic acids, is reabsorbed from filtrate by active transport, and a small portion is actively secreted into the urine.
- The proximal tubule is the site of most secretion, reabsorption, and active transport.
- The enzyme isoforms seem to have a tissue-specific expression, showing the highest expression levels in cells where intense active transport is expected to occur.
- The electrocytes establish a charge difference across the cell membranes, presumably by active transport of ions.
