Question

select the choice(s) that characterizes each of the following statements
a diffusion
b osmosis
c endocytosis
d exocytosis
e filtration
f phagocytosis
g pinocytosis
20 requires atp
21 driven by fluid pressure
22 flows from an area of greater pressure to lesser pressure
23 moves water through a semipermeable membrane
24 provides for cellular uptake of solid or large particles from the cell exterior
25 transports amino acids, some sugars and sodium through the plasma membrane

Explanation:

• 20: Endocytosis (C), Exocytosis (D), Phagocytosis (F), Pinocytosis (G) are active - transport processes that require ATP for energy.
• 21: Filtration (E) is driven by fluid pressure.
• 22: Diffusion (A) is the movement from an area of greater pressure (or concentration) to lesser pressure (or concentration).
• 23: Osmosis (B) is the movement of water through a semi - permeable membrane.
• 24: Phagocytosis (F) is the cellular uptake of solid or large particles from the cell exterior.
• 25: Pinocytosis (G) transports amino acids, some sugars and sodium through the plasma membrane.
