Transport
This uniporter is known to help a specific ion or molecule travel in one direction
Protein
What are the two parts of a phospholipid?
-Hydrophilic head
-Hydrophobic tail
The nickname for this giant in the sky is the "Red Planet"
What is Mars?
The number of sodium ions pumped out for every two potassium ions pumped in.
What is 3?
This is the main component of the cell membrane, arranged in a bilayer with hydrophilic heads facing out.
What is a phospholipid.
What type of passive transport is characterized as the movement of water molecules across a plasma membrane (the membrane is impermeable to solute).
Osmosis
What characteristic of a cell is shared by all cells?
Plasma Membrane
Our galaxy and a candy bar have this same name.
What is the Milky Way?
The molecule that provides the energy for the pump's action.
What is ATP?
The current model describing the membrane as a mosaic of proteins drifting in a sea of lipids.
What is the Fluid Mosaic Model?
What type of active transport utilizes the electrochemical gradient as an energy source?
Active Transport
What are the 4 components of the plasma membrane?
-Phospholipids
-Proteins
-Carbohydrates
-Cholesterol
This sea dweller has 3 hearts.
What is an Octopus?
Since this process moves ions against their concentration gradients and requires energy, it's classified as this.
What is active transport?
This steroid lipid is embedded in the cell membrane and helps maintain its fluidity, especially at varying temperatures.
What is cholesterol?
What number of ions are moving in and out of the cell during a sodium potassium pump?
3 Na+ out of the cell and 2 K+ into the cell
This is the water-loving, phosphate-containing "head" of a phospholipid molecule.
What is a hydrophilic head?
The largest organ in the human body.
What is skin?
What kind of active transport is the sodium potassium pump?
Primary Active Transport
The property of the cell membrane that allows some substances to pass through while blocking others.
What is selective permeability?
Why is the sodium potassium pump considered a type of active transport?
-Keeps putting more sodium outside the cell where there is already a high concentration.
-Keeps putting more potassium inside the cell where there is already a high concentration.
What kind of molecules flow through the lipid bilayer easily?
-Easily: small, non polar
This loud natural phenomenon in the sky scares dogs and humans alike and is hotter than the surface of the sun when it appears.
What is lightening?
(T/F) The energy source for active transport is always ATP.
False
These protein structures create pathways through the lipid bilayer, allowing specific charged or large molecules to pass through.
What are channel proteins?
