Cells
The smallest units of life
What are cells?
The structure that regulates what enters and exits the cell?
What is the cell membrane?
Transport that does not require energy.
What is passive transport?
The energy carrying molecule that gives the energy required for active transport.
What is ATP / Adenosine Triphosphate?
Quintiple Jeopardy = X5 Points
Osmosis is considered this type of transport.
What is passive transport?
Prokaryotic cells use these structures to attach to each other and exchange plasmids.
What are pili?
Quadruple Jeopardy = X4 Points
The three types of passive transport
What are Diffusion, Osmosis and Facilitated diffusion?
The movement of molecules from high concentration to low concentration until dynamic equilibrium is reached.
What is diffusion?
Active transport that keeps sodium from building up in the cell.
What is a sodium potassium pump?
This solution has an equal number of solutes in and outside the cell.
What is isotonic.
A structure within a cell that performs a specific function.
What is an organelle?
Diffusion of water.
What is osmosis?
Molecules that are too large to move into the cell directly through the phospholipid bilayer are brought in through this process.
What is endocytosis?
Triple Jeopardy = X3 Points
Which type of molecule forms a lipid bilayer within a cell?
What is a phospholipid?
These act as channels to allow molecules to move in and out of the cell.
What are proteins?
The movement of molecules across a membrane with the help of a protein. Does not require energy.
What is facilitated diffusion?
the use of Pseudopodia in engulfing large food particles into the cell
What is Phagocytosis?
Double Jeopardy = X2 Points
Solution with a low solute concentration on the outside, making the cell swell.
What is hypotonic?
A vesicle's membrane fuses with the cell membrane, forcing the contents of the vesicle outside of the cell.
What is exocytosis
They function as identification markers on the cell membrane.
What are glycoproteins?
These types of molecules move easily through a cell membrane.
What are small, nonpolar molecules.
During active transport molecules move in this direction across the cell membrane.
What is from low concentration to high concentration? Against the concentration gradient.
After diffusion or osmosis a cell will be in this state.
What is Equilibrium (Accept homeostasis?)
Double Jeopardy =X2 Points
