Passive Transport and Active Transport

Question 1

Passive- Diffusion

Answer 1

the net movement of particles across a membrane to a region of lower solute concentration (along solute concentration gradient)
requiring no energy

Question 2

passive- facilitated diffusion

Answer 2

the net movement of particles across a membrane to a region of lower solute concentration (along solute concentration gradient) requiring the assistance of transmembrane proteins
requiring no energy

Question 3

Passive- osmosis

Answer 3

the net movement of water across a membrane to a region of higher solute concentration
requiring no energy

Question 4

Active- active transport

Answer 4

the net movement of particles across a membrane to a region of higher solute concentration (against the solute concentration gradient)
requiring energy (ATP) and the assistance of a protein carrier

Question 5

Active- endocytosis

Answer 5

a process of cellular ingestion involving the plasma membrane folding inward to bring substances into the cells inside a vesicle

Question 6

Active- Exocystosis

Answer 6

a process of cellular secretion or excretion involving substances contained in vesicles being discharged from the cell by fusion of the vesicle membrane with the plasma membrane.
