vesicles!

• ligands stick to cargo receptors inide the vesicles
• clathrins coat the vesicle, forming a cage around it and making the vesicle circular
• coat proteins can be used for different routes
• adaptins connect the clathrins to the cargo receptors
• dynamins close the vesicles when they're ready to be transported
• inactive adaptin releases the clathrins
• transferrin proteins carry iron in blood
• vesicles move using microtubules
• kinesins move towards the posive end of the microtubule
• dyneins move towards the minus end of the microtubules
• vesicles use SNARES to to fuse with the membrane of the target
