types of active transport

what are the two types of active vessicular transport

exocytosis

endocytosis

describe what happens during exocytosis

cellular products and waste are transported via vesicle to membrane where vesicle fuses releasing content into extracellular environment

how glycoproteins and glycolipids integrate into cell membrane

describe endocytosis

ingestion of fluid or large particles

cell membrane folds inwards engulfing material and pinching off into vesicle

what are the two types of endocytosis

pinocytosis

receptor mediated endocytosis

describe pinocytosis

non specific ingestion of fluid

describe receptor mediated endocytosis

form of endocytosis that targets contain molecules that are in low concentration outside of the cell

molecules bind to receptor membranes which then invaginates to form a vesicle

what are the two types of active transport

primary active

secondary active

describe primary active transport

pumping of solutes by carrier protein and hydrolysis of ATP

phosphate group binds causing conformational change in the carrier protein

describe secondary active transport

ATP generates an electrochemical gradient where two solutes are moving on

symport is when both solutes move in same direction

antiport is hwen solutes move in opposite direction

what is the product of ATP hydrolysis

ADP and phosphate group
