cells Flashcards
the function of nuclear pore
to allow passage of large molc
function of cytoplasm
metabolic reactions site
function of vacuole
isolates waste products
plasma membrane features 2
selective barrier, cell receptors
mitochondria role
site of aerobic respiration, ATP synthesis
ribosomes used in
protein synthesis
R endoplasmic reticulum
protein synthesis site
S endoplasmic reticulum 4
lipid+cholesterol synthesis, lipid metabolism, drug detox
golgi apparatus 5
- packages
- modifies
- segregates proteins from cells
- inclusion in lysosomes
- incorporation in plasma membranes
peroxisomes
enzymes detox toxic substances
lysosomes
intracellular digestion -phagocytosis
microtubules 3
support cell
gives shape
intracellular and cellular movement
microfilaments
muscle contraction- form cell cytoskelaton
intermediate filaments 2
stable cytoskeleton elements
resist mechanical forces acting on cell
centrioles
organize microtubule network during mitosis (spindle)
nuclear envelope
separates nucleoplasm from cytoplasm
nucleus
genetic info
protein synthesis
mrna
trna
nucleolus
site of the ribosome subunit manufacture
chromatin 3
dna around histones, carry instructions to build proteins (chromosomes in mitosis)
Fluid mosiac model
phos bilayer- not rigid, but fluid and flexible where protein are embedded in lipid bilayer
membrane proteins have a variety of functions 3
- transport of molc in and out of the cells
- receptors for various chemical messages e.g hormones
- important in cell attachements
dorsal body cavity
cranial cavity and spinal cavity
ventral body cavity
thoracic cavity, diaphragm, abdominopelvic cavity
thoracic cavity
mediastinum left and right pleural cavity (lungs), pericardial cavity (heart)
abdominpelvic cavity
abdominal cavity, pelvic cavity
abdominal cavity 6
stomach, liver, spleen, kidneys, small and most large intestine
pelvic cavity
bladder, reproductive organs
