Membrane consist of what

Fluid dynamic phospholipid bilayer

What forms a mosaic pattern?

What do mosaic patterns do?

Embedded proteins

Provide structural integrity and perform many functions

What projects from outer surface

What is equalLibrium

The hydrate chains

Molecules diffuse equally in a given space

What is permeability

What is permeable

Allowing some substances to pass through freely while others do not

The plasma membrane

What is passive transport

What does passive transport require

Movement from high concentration to low concentration

No energy…required diffusion and Kinetic Energy

Felicitated diffusion is like…

Passive transport.

Where does water always moves

Smooth ER has no what

What is active transport

Hypertonic solution

Ribosomes

Transports molecules from low concentration to high

What does active transport require

What is exocytosis

Carrier proteins, ATP, and a concentration gradient

Vesicle mediated transport (transports sell products and waste out of the soap by vesicle formation) coming from goilgi apparatus packaged in vesicle

What is Pinocytosis

What is phagocytosis

Liquid or small particle cell drinking

Large particles cell eating
for example white blood cells eating a bacteria

What are vesicles do What have a hard time moving through cell membrane

Containers that fuse with outer membrane Charge molecules and ions and macromolecules

What is diffusion What drives diffusion What can diffuse freely across cell membrane

Movement of Molecules from an area of high concentration to an area of low concentration Kinetic Energy Lipid soluble molecules gases and small water soluble molecules

What is osmosis What is Osmotic pressure

Diffusion of water across a semi permeable membrane. Due to a number of non-diffusible particles in a solution Force that causes water to move in a direction

Hypotonic solutions Hypertonic solutions

Solution that contains less particles then some other solution cause cell to swell or burst More particles than other solutions causes cell to shrink or crenate

Isotonic solution What is salute

Solution that contains equal amounts of solute compared to other solutions and have no change Particles

Carrier proteins are What is felicitated transport Active transport

Specific for the molecules they transport Passive mechanism transport from high to low concentration Transports against concentration gradient

Passive transport The sodium potassium pump Na+

No carrier protein Involved in active transport of sodium potassium Has hard time getting through carrier proteins

What is exocytosis

Vesicle containing sell products fuse with plasma membrane | Products are released and vesicle membrane become a part of the plasma membrane

What is endocytosis What does invaginate mean

An area of the cell membrane is turned inside out and surrounds a substance than pinches off in the form of a vesicle Turn inside out

Receptor

Mediated specific type of Pinocytosis which occurs in response to a receptor simulation

All cells are not Membrane phospholipids can Lysis

Motile Drift into plasma membrane Disintegration of a cell by rupture of it cell wall or membrane

Hypotonic animal cells will Chloroplast helps the process of What is responsible for membrane transport

Lyse Photosynthesis Proteins

Cyanide

Salt
