mechanisms of intracellular transport

   What is method of transport where the substance passes through the membrane in the direction of its concentration gradient using a special transport protein?

• simple diffusion

• facilitated diffusion

• active transport

• endocytosis

The movement of a small molecule or ion across a membrane due to a difference in concentration or electrical charge

• passive transport

• transcellular transport

• active transport

• pinocytosis

General term for a membrane-embedded protein that serves as a carrier of ions or small molecules from one side of the membrane to the other

• membrane transport protein

• Antiporter

• symporter

• P-type pump

Movement of a molecule across a membrane that is driven by ATP hydrolysis or other form of metabolic energy

•   facilitated diffusion

• simple diffusion

• phagocytosis

• active transport

Membrane carrier protein that transports two different ions or small molecules across a membrane in opposite directions, either simultaneously or in sequence

• symporter

• аntiporter

• uniporter

• caveolin

Carrier protein that transports two types of solute across the membrane in the same direction

• symporter

• аntiporter

• uniporter

• caveolin

Specialized class of tiny secretory vesicles that store neurotransmitter molecules

• endocytic vesicle

• phagocytic vesicle

• synaptic vesicle

• transport vesicle
