Diffusion
The direction that particles move during diffusion
What is from high to low concentration?
Membranes that only allow certain substances to move across them.
What are selectively permeable membranes?
Energy is required for materials to move across a cell membrane.
What is active transport?
Liquid is brought or engulfed into the cell through a vesicle.
What is pinocytosis?
This deals with multicellular organisms and it's arrangement of specialized parts. The levels becomes more complex as the increases
What is Levels of Structure or Levels of Organization?
Uses channels or carrier protein to transport molecules in and out of the cell membrane
What is facilitated Diffusion?
The direction of water movement when the solution is hypertonic.
What is out of the cell?
The process to when ATP dephosphorylates, removing a phosphate group and replacing it with a water molecule (H2O).
What is hydrolysis?
Vesicles taking substances out of the cell.
What is exocytosis?
A difference in the concentration of a substance across a space.
What is concentration gradient?
Water molecules move in a area where ?
What is the highest solute concentration ?
Osmosis is this type of transport and does not require carrier proteins.This falls with which type of transport
What is passive transport?
When energy is broken down and released
What is ADP?
Molecules too large to pass through are engulfed into the cell through this process.
What is endocytosis?
These types of proteins are usually embedded in the cell or on the surface of the cell
What is integral and peripheral proteins?
When substances move down the concentration gradient without the use of channel proteins
What is simple diffusion?
Causes a cell to swell.
What is a hypotonic solution?
The process of taking in large food particles
What is phagocytosis?
Carbohydrate Chains
What is helping cells recognize each other and providing protection for cells?
The main type of cell transport that diffusion falls under.
What is passive transport?
True or False? The resting membrane potential is a process when electrical activity within the plasma membrane is activated -causing the movement of molecules going in and out of the membrane
What is false ?
Larger molecules like hormones are removed from the cell during this process.
What is exocytosis?
3 main parts of Adenosine Triphosphate
What is adenine (protein), ribose (sugar) and 3 phosphate groups.
