Openstax Ch. 5 Vocabulary Cell Membrane Vocabulary Test

____________ uses energy to move solutes against their gradients.

. is considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need to do just about everything we do.

_________ channel used exclusively to facilitate the movement of water through the bilayer.

___________ undergo a subtle change in shape that translocate the solute binding site across the membrane. The shape change may be triggered by binding and release of the transported molecule. No net energy input required.

Since active transport moves substances against their concentration gradients it requires energy, usually in the form of ______.

__________ provide corridors that allow a specific molecule or ion to cross the membrane.

_______ is the tendency for molecules to spread out evenly into the available space. From higher concentration to lower.

the cell takes in molecules and particulate matter by forming new vesicles from the plasma membrane.

transport vesicles migrate to the membrane, fuse with it, and release their contents.

In_______________________transport proteins speed the passive movement of molecules across the plasma membrane.

The _______________states that the membrane is a mosaic of protein molecules bobbing in fluid bilayer of phospholipids.

______________molecules, such as hydrocarbons can dissolve in the lipid bilayer of the membrane across it easily.

solute concentration is greater than that inside the cell; cell loses water.

In a _______ environment, plant cells lose water; eventually, the membrane pulls away from the wall, a usually lethal effect called ________.

solute concentration is less than that inside the cell; cell gains water.
