Endocytosis (phago and pinocytosis) and exocytosis (active transport) Flashcards
(17 cards)
what does endocytosis doe?
engulfs substances by enclosing them into vesicles
what does phago do?
engulfs large particles like bacteria and debris
what forms around phago particles?
phagosomes
what happens when phagosomes and lyosomes combine?
it breaks down the contents of the rest of the particle
what is one of the benefits of phago?
helps fight against pathogens
what does pinocytosis do?
ingests fluids and dissolves substances
what happens when the cell membrane encloses in pinocytosis?
forms small vesicles filled with fluid
does pinocytosis involve large particles?
no
what is pinocytosis important for?
nutrient absorption
what is the role of exocytosis?
transports materials out of cells using vesicles
what is the benefits of exocytosis?
removes waste and releases hormones
what two parts of exocytosis combine with each other to release contents out of the cell?
golgi apparatus and the cell membrane
what does exocytosis require?
ATP
molecules in exocytosis can either be…
continuously released or signalled to be released
what is active transport?
the movement of substances from a low concentration to a high concentration
why is it called “active” transport?
because it uses energy that is always active
what are exchanged through membranes through active transport?
ions
