2. The assignments are the second and
eighth questions on Slide 6 and 7.
Please hand them over to the class
commissary in charge of studies first,
and then the class commissary will send
them to my email 66235109@qq.com in
a compressed package before March
22, 2020.

active transport
form of transport across the cell membrane that requires input of cellular energy
amphipathic
describes a molecule that exhibits a difference in polarity between its two ends, resulting in a difference in water solubility
cell membrane
membrane surrounding all animal cells, composed of a lipid bilayer interspersed with various molecules; also known as plasma membrane
endocytosis
import of material into the cell by formation of a membrane-bound vesicle
exocytosis
export of a substance out of a cell by formation of a membrane-bound vesicle
facilitated diffusion
diffusion of a substance with the aid of a membrane protein
glycocalyx
coating of sugar molecules that surrounds the cell membrane
glycoprotein
protein that has one or more carbohydrates attached
hydrophilic
describes a substance or structure attracted to water
hydrophobic
describes a substance or structure repelled by water
integral protein
membrane-associated protein that spans the entire width of the lipid bilayer
passive transport
form of transport across the cell membrane that does not require input of cellular energy
peripheral protein
membrane-associated protein that does not span the width of the lipid bilayer, but is attached peripherally to integral proteins, membrane lipids, or other components of the membrane

endocytosis of large particles
pinocytosis
endocytosis of fluid
receptor-mediated endocytosis
endocytosis of ligands attached to membrane-bound receptors
selective permeability
feature of any barrier that allows certain substances to cross but excludes others
sodium-potassium pump
