11_Active transport by which macromolecules transported to the inside of the cell containing ECF:
a_ pinocytosis
b_ phagocytosis
c_ exocytosis

True or False

1_phagocytosis is engulfing large particles with ECF (T/F)



2_In Sodium glucose pump Sodium is carried to the cell by a carrier and glucose diffuse passively
(T/F)

3_pinocytosis is called cell eating (T/F)

4_passive transport needs energy (T/F)

5_passive transport is inversely proportional with lipid solubility of substance (T/F)

6_simple diffusion needs carrier (T/F)

7_Leak channels have gates (T/F)

8_Gated channels have no gates (T/F)

9_voltage channels are leakage channels (T/F)

10_Ligand channels are gated channels (T/F)

11_Facilitated diffusion needs carrier (T/F)

12_Most amino acids are transported by active transport (T/F)

13_simple diffusion has saturation (T/F)

14_Osmosis means diffusion under hydrostatic pressure while filtration means diffusion under
osmotic pressure (T/F)
