Name: _________________________________________________ Date: _______________ Period: ________ Biology Notes: Active Transport Directions: Fill in the blanks as we cover the topic in the PowerPoint. Active Transport • Defined: Molecules move from a ____________________ to a ____________________ concentration. – • ATP _______________ opens/closes _________________ _____________________ – • _______________________ (up) the concentration gradient ATP = Adenosine __________phosphate Acts like a _________________ Endocytosis • Endocytosis: Process in which the ____________________ membrane takes _______ substances (2 types). 1. Phagocytosis: when a cell ____________________ a ____________________ particle. a. ___________ are called phagocytes 2. Pinocytosis: when a cell ____________________ a ____________________ particle. • Unfortunately, ____________________ can also enter our cells this way. Exocytosis • Defined: Process when substances are ____________________ from the cell • Proteins, ____________________, and waste ____________________ by exocytosis • Vesicle carry & ____________________ objects through the plasma ____________________ Review 1) How are active and passive transport different? Similar? 2) Which molecule powers active transport? 3) How are endo‐ and exocytosis similar? Different? 4) Which cell part controls active transport? 5) Once inside a cell, what actually kills bacteria that have been swallowed by endocytosis? 6) During exocytosis, which organelle fuses with the cell membrane? 7) What are the types of endocytosis?
