A.
binding of specific solutes to receptors triggers vesicle formation
B.
saturated fatty acids, unsaturated fatty acid and cholesterol
C.
This model states that the membrane is a mosaic of protein molecules bobbing in a fluid bilayer of phospholipids
Question #2
Match the term and its description. lipids
A.
Proteins are bound to the surface of the membrane
B.
also called cell drinking, molecules dissolved in droplets are taken up when extracellular fluid is "gulped" into tiny vesicles
C.
saturated fatty acids, unsaturated fatty acid and cholesterol
Question #3
Match the term and its description. peripheral proteins
A.
Membranes have distinct inside and outside faces
B.
transport vesicles migrate to the membrane, fuse with it, and release their contents outside the cell
C.
Proteins are bound to the surface of the membrane
Question #4
Match the term and its description. carbohydrates
A.
Membranes have distinct inside and outside faces
B.
This is the tendency for molecules to spread out evenly into the available spaces
C.

A.
a transport protein that generates voltage across a membrane
B.
This is the tendency for molecules to spread out evenly into the available space
C.
the diffusion of a substance across a biological membrane without the expenditure of energy

Match the term and its description. passive transport
A.
The voltage across a membrane
B.
the diffusion of a substance across a biological membrane without the expenditure of energy
C.
This is the ability of a surounding solution to cause a cell to gain or lose water
Question #7
Match the term and its description. tonicity
A.
the control of solute concentartion and water balance, is a necessary adaptation for life in such environments
B.
This transport requires energy, usually in the form of ATP hydrolysis, to move substance against their concentration gradients
C.
This is the ability of a surrounding solution to cause a cell to gain or lose water
Question #8
Match the term and its description. osmoregulation
A.
the control of solute concentrations and water balance, is a necessary adaptation for life in such environments
B.
These ion channels open or close in response to a stimulus
C.
the membrane pulss away form cell wall, causing the plant to wilt
Question #9
Match the term and its description. plasmolysis
A.
This is type of passive transport aided by chanel proteins and carrier proteins
B.
The voltage across a membrane
C.
the membrane pulls away from cell wall, causing the plant to wilt

A.
These ion channels open or close in response to a stimulus
B.
the membrane pulss away form cell wall, causing the plant to wilt
C.
This is type of passive transport aided by channel proteins and carrier proteins
Question #11
Match the term and its description. gated channels
A.
These ion channels open or close in response to a stimulus
B.
This transport requires energy, usually in the form of ATP hydrolysis, to move substance against their concentration gradients
C.
the control of solute concentartion and water balance, is a necessary adaptation for life in such environments

a transport protein that generates voltage across a membrane
C.
The voltage across a membrane
Question #14
Match the term and its description. an electrogenic pump
A.
This is the tendency for molecules to spread out evenly into the available spaces
B.
A coupled active transport by a membrane protein. It occurs when active transport of a solute indirectly drives transport of other substance

A.
A coupled active transport by a membrane protein. It occurs when active transport of a solute indirectly drives transport of other substances
B.
Membranes have distinct inside and outside faces
C.
transport vesicles migrate to the membrane, fuse with it, and release their contents outside the cell
