Cell Transport

Information about the cell membrane and transport

QuestionAnswer
The primary molecule that forms a cell membrane Phospholipid
Water loving Hydrophilic
These three types of molecules can diffuse through the cell membrane without help Small molecules, nonpolar molecules, and some water molecules
This phrase describes how molecules in the cell membrane float together unattached Fluid Mosaic model
This phrase describes the cell membrane's ability to control what enters and leaves Selectively permeable
The process by which a solute Will spread from an area of high concentration to Low concentration Diffusion
This word describes a condition where one area in a solution has a higher concentration than another Concentration gradient
Passive transport moves this way relative to the gradient Down or with the gradient
Passive transport is different from active transport in this important way It does not use energy
Large molecules may diffuse through the cell membrane with the help of these molecules Channel proteins
When water moves across the cell membrane due to a difference in concentration Osmosis
This form of active transport involves moving material into the cell Endocytosis
This part of a phospholipid is hydrophilic The head
This part of a phospholipid faces away from water The tails
Based upon the arrangement of the phospholipids, the cell membrane has been described using this two word term Phospholipid bilayer
ATP is used to open or close a special channel protein in this form of active transport Protein pump
Water will flow out of a cell if it is placed in this type of solution Hypertonic
Water fearing Hydrophobic
An animal cell may swell and burst in this type of solution Hypotonic
Controlling the material that moves in and out of the cell helps living things maintain this Homeostasis
If I have a cell in an isotonic solution, what would most likely happen if I added salt to the solution The cell would shrink
This form of active transport involves moving material out of the cell Exocytosis
If a large molecule uses a protein to move across the cell membrane without using any energy, it is this specific form of transport Facilitated diffusion
3 forms of passive transport Diffusion, facilitated diffusion, osmosis
