CHE SIGNIFICA ACTIVE TRANSPORT IN INGLESE
Trasporto attivo
Il trasporto attivo è il movimento delle molecole attraverso una membrana cellulare nella direzione contro il loro gradiente di concentrazione, vale a dire passando da una bassa concentrazione ad una concentrazione elevata. Il trasporto attivo è di solito associato ad accumulare elevate concentrazioni di molecole che la cellula necessita, come ioni, glucosio e aminoacidi. Se il processo utilizza l'energia chimica, come adenosine trifosfato, viene definito il trasporto attivo primario. Il trasporto attivo secondario comporta l'utilizzo di un gradiente elettrochimico. Il trasporto attivo utilizza l'energia cellulare, a differenza del trasporto passivo, che non utilizza l'energia cellulare. Il trasporto attivo è un buon esempio di un processo per cui le celle necessitano di energia. Esempi di trasporti attivi includono l'assunzione di glucosio negli intestini nell'uomo e l'assorbimento di ioni minerali nelle cellule di capelli radice delle piante.
definizione di active transport nel dizionario inglese
La definizione di trasporto attivo nel dizionario è un processo mediante il quale le molecole sono abilitate a passare attraverso una membrana da una regione in cui sono in una bassa concentrazione a una di alta concentrazione; ciò richiede il dispendio di energia nel metabolismo ed è assistito da proteine di trasporto, comunemente chiamate pompe.
