Term
Structure of plasma membrane of cell |
|
Definition
phospholipid bilayer studded with proteins |
|
|
Term
Function of plasma membrane of cell |
|
Definition
Boundary of cell: carbohydrates and proteins on outer surface of cell membrane perform various functions |
|
|
Term
|
Definition
Tiny particles, each are made of rRNA subunits |
|
|
Term
|
Definition
rough: receives and transports synthesised proteins smooth:synthesises lipids and certain carbs |
|
|
Term
Structure of golgi apparatus |
|
Definition
stack of flattened membranous sacs |
|
|
Term
Function of golgi apparatus |
|
Definition
chemically process and package substances received from ER |
|
|
Term
|
Definition
Synthesis of ATP (power supply) |
|
|
Term
Structure of mitochondria |
|
Definition
own DNA. Enzymes embed a folded internal membrane. A membranous capsule covers the internal membrane |
|
|
Term
|
Definition
membrane encasing hydrolysis enzymes |
|
|
Term
|
Definition
breaks up large molecules |
|
|
Term
|
Definition
Two membranes encapsulating DNA |
|
|
Term
|
Definition
form ribosomes by forming subunits |
|
|
Term
|
Definition
particle movement from high to low concentration through a membrane |
|
|
Term
|
Definition
selectively permeable membrane (which has at least one impermeant solute present) allows movement of water through |
|
|
Term
|
Definition
movement of small solute particles and H2O through filtration membrane. Low to high conc. gradient |
|
|
Term
3 types of active transport processes |
|
Definition
ion pump, phagocytosis, pinocytosis |
|
|
Term
|
Definition
carrier protein molecule moves solute particles from high to low area concentrations |
|
|
Term
|
Definition
section of plasma membrane allows movement of a cell or large particles by trapping and pinching particle or other cell off into the cell |
|
|
Term
|
Definition
Section of plasma membrane pinches off to allow movement of fluid and dissolved molecules into cell |
|
|
Term
which ions enter and exit Na-K pump and how many |
|
Definition
3 Na ions out of cell, 2 K ions into cell |
|
|
Term
describe process after large particle enter cell by phagocytosis |
|
Definition
cytoskeleton of cell extends plasma membrane of cell, which forms a pocket to surround target called a vesicle. Target is pulled by cytoskeleton movement. Vesicle fuses with lysosomes to break down the target particle |
|
|
Term
|
Definition
bacterial infection. Cell lining of intestines leak Cl-. H2O follows Cl- by osmosis. Severe diarrhoea, loss of body water |
