Name: _________________________________________________ Date: _______________ Period: ________ Biology Notes: Active Transport Directions: Fill in as we cover the topic in the PowerPoint. Corresponds to pages 89 – 91 in your textbook. Active Transport • Defined: Molecules move from a ____________________ to a ____________________ concentration. – _______________________ (up) the concentration gradient • ATP _______________ opens/closes _________________ _____________________ – • 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. Additional Info Exocytosis • Defined: Process when substances are ____________________ Additional Info 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? How are they different? _________________________________________________________________________________________ _________________________________________________________________________________________
