WHATS THIS UNIT CALLED? Flashcards
takes place when ions or particles labeled as solutions begin to move from a higher concentration of particles in a solution to lower concentration particles
Concentration gradient
The movement of molecules from an area of high concentration to an area low concentration until it is equal on both sides
Diffusion
Through the phospholipid bilayer, happens to the small and nonpolar particles
Simple diffusion
Through the transport protein, happens to large or polar particles.
Facilitated diffusion
goes through the channel protein
Facilitated diffusion
goes right through the cell membrane.
Simple diffusion
To explain the organization and structure of the plasma membrane based on theorematic principles
Fluid mosaic model
A condition in which the internal environment of the body remains relatively constant despite changes in the external environment.
Homeostasis
Examples would be the maintenance of the body temperature and levels of glucose in the blood
Homeostasis
doesn’t use energy
Passive
goes against the concentration gradient
Active
Pumps
Endocytosis
Exocytosis
Types of active transports-
An active transport that takes in particles
Phagocytosis
the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy
Active transport
No ATP needed, with concentration gradient
Passive
