This is made of phosphate and is hydrophilic and polar.
What is a phospholipid head?
This is a tunnel for molecules and is used in passive transport.
What is a channel protein?
This term tells you something is repelled by water.
What is hydrophobic?
This energy is used in our body for different processes. Its full name is adenosine tri phosphate.
What is ATP?
This term tells you something is attracted to water.
What is hydrophilic?
This is a term used for a more concentrated solution compared to what is around it.
What is hypertonic?
This is made of lipid (fatty acids) and is hydrophobic and nonpolar.
What is the phospholipid tail?
This means that only some things are allowed to pass through.
What is semipermeable?
These molecules have ends with opposite charges.
What are polar molecules?
This is a term for a solution that is less concentrated compared to what is around it.
What is hypotonic?
This type of transport is passive but does use a channel protein.
What is facilitated diffusion?
This type of transport uses energy and goes against the concentration gradient.
What is active transport?
These are two reasons a molecule would not be able to pass straight through the cell membrane.
What are large or charged?
This term means staying balanced, a sort of equilibrium.
What is homeostasis?
This type of protein is used in active transport for things like ions.
What is a protein pump?
This is a molecule that is neutral throughout.
What is a nonpolar molecule?
This means passively spreading out toward lower concentrations.
What is diffusion?
This stabilizes the phospholipid bilayer.
What is cholesterol?
These biological molecules form both channels and pumps in the cell membrane.
What are proteins?
This is a channel protein especially for water to pass through.
What is an aquaporin?
This is diffusion specifically for water.
What is osmosis?
This is when a large package to go into the cell does so by wrapping cell membrane around it and breaking off as a vesicle.
What is endocytosis?
This is a sort of scale of high concentration to low concentration.
What is a concentration gradient?
This is a charged atom.
What is an ion?
This is when a large package needs to leave the cell, so a vacuole fuses with the cell membrane to get out.
What is exocytosis?
