How would you define cellular diffusion?
Cellular diffusion is when molecules in the cell go from high concentration to low concentration to balance out the concentration. Small molecules can diffuse through the cell membrane, but larger molecules need the help of proteins. This is call facilitated diffusion.
Molecules move in and out freely from high to low concentration?
Due to diffusion pressure gradient through the cell wall
What are the 3 rules for the cell theory?
1. Moving from high concentration to low concentration. 2. Balances out molecules.
What is high energy molecules used by cells?
Adenosine TriPhosphate is a high energy molecule used in the Kreb cycle of the mitochondria, the powerhouse of the cell.
How does a cell each equilibrium?
Molecules tend to travel from a concentration from high to low. A cell will reach equilibrium when the concentration gradient has become equal on both sides of a cell (inner and outer membrane). A cell will reach what is called "dynamic equilibrium" when the concentration gradient of a cell is equal, but molecules still move back and forth in the same proportions.
Does an increase or decrease in potassium extracellular ions hyperpolarize a cell?
An extracellular increase of potassium (increase of intracellular Sodium) causes depolarization. The opposite, I presume, meaning high intracellular potassium (inside cell) and high extracellular sodium (outside cell) would be hyperpolarization
When the salt level is high inside a cell what type of molecules can passively move into the cell?
A high level of salt in a cell would cause water molecules to move passively into the cell.
Glucose is a molecule that can move across the cell membrane if the concentration of glucose is high or inside the cell than outside the cell then what will happen by the process of diffusion?
glucose molecules will diffuse out of the cell. apex
What are the name of high energy molecules that run the cell's machinery?
adenosine triphoshate
If water moves into a cell and the cell swells what terms describes the environment inside the cell?
The term you're looking for is hypotonic, which basically refers to having reduced pressure or tone. In Biology, hypotonic refers to having a lower osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid.
What term describes this action does it require energy?
1.Small lipid molecules are in high concentration outside a cell. They slowly cross the membrance into the cell. 2. Ions are in low concentration outside a cell they move rapidly into the cell via protein molecules.
Why is active transport of molecules necessary?
To move substances from low to high concentration.

How does the ecf vary from the icf?
In terms of location,ecf vary from the icf in that they are separated by the cell membranes. In terms of composition, the intracellular fluids are high in potassium and magnesium and low in sodium and chloride ions.
What is cell diffusion?
One way that substances enter a cell is through diffusion. Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration. When the molecules are even throughout a space it is called equilibrium.
Molecules move in and out freely from high to low concentration?
Due to diffusion pressure gradient through the cell wall
