What is the macromolecules for lysosome
phospholipids, proteins (enzymes)
What is the Peroxisome similar to
lysosome
What is a peroxisome
single membrane surrounding enzymes that break down molecules by oxidizing them, which forms H2O2
Why is peroxide broken down
because it is toxic so it is broken into water
What is the golgi body function

makes complex carbohydrates
package for secretion
What is the structure for the golgi body
flat membrane pockets, cisternae, filled with enzymes
what is macromolecules for golgi body
phospholipids, proteins
what is the rough endoplasmic reticulum function
fold and transport proteins, add carbs to glycoproteins, produces membrane (makes phospholipids and embedded proteins).
What is the structure of the rough endoplasmic reticulum
tunnels made of lots of enzymes ribosomes
What is the macro molecules for the rough endoplasmic reticulum
phospholipids and proteins
What is the function of cytoplasm
everything that happens between cell membrane and nucleus
What is the structure of cytoplasm
all organelles between nucleus and cell membrane
all fluid that fills cell= cytosol
What is the macro molecules of cytoplasm
all
What is the function of ribosome
make proteins
how ribosomes make proteins
1) connect amino acids in correct order
2) follow directions from RNA
3) free ribosomes; cytoplasmic proteins
4) bound ribosomes; proteins for secretion, membranes or organelles
What is the structure of ribosomes
two subunits
protein subunit
RNA subunit
What is the mitochondrion function
cellular respiration
uses oxygen to burn glucose and give cell energy
What is the macro molecules for chloroplasts
phospholipids, protein, nucleic acids
What is the structure for the mitochondrion
oval outer membrane
folded inner membrane (folds called cristae)
What is the macromolecules for the mitochondrion
phospholipids, protein, nucleic acids
What is the function of the cell wall
physical protection and structural support
What is the vacuole function
storage and support plants
What is the structure for chloroplasts
oval outer membrane
grana= stacks of disks
What is the structure of the cell wall
wall surrounding cell
has holes like windows in a wall
What is the function for chloroplasts
photosynthesis
converts solar energy into chemical energy
What is the formula for photosynthesis
CO2+H2O - Glucose + O2
What is the macro molecules for the cell wall
cellulose
What is the function for the cell membrane
controls what enters and leaves the cell
What is the structure of the cell membrane
flexible lining just inside cell wall
What is the macro molecule for the cell membrane
`phospholipids
proteins
Cholesterol
cellular respiration formula
O2 + glucose- CO2 and energy
What is the structure of the nucleus
nuclear envelope
nuclear pores
chromosomes
nucleolus
nuclear envelope
double layer of membrane around nucleus
nuclear pores
holes in envelope
chromosomes
DNA inside nucleus
nucleolus
area full of ribosome parts
What is the function of the nucleus
store DNA and direct cell
What is the macro molecules for the nucleus
phospholipids
proteins, nucleic acids
What is the function of the smooth endoplasmic reticulum
transport proteins, detoxify poisions/ drugs, produce triglycerides, steroids, and phospholipids
What is the structure smooth endoplasmic reticulum
membrane tunnels full of enzymes
What is the macromolecules for smooth endoplasmic reticulum
phospholipids and proteins
What is the function cytoskeleton
internal mechanical support
moves organelles vessicles
What is the structure for the cytoskeleton
framework of microtubules (support) and motor proteins (movement)
What is the macro molecules for cytoskeleton
protein
What is the cytoskeleton elements (animal and plant)
microtubules
microfilaments
intermediate filaments
What are microtubules
largest, hollow tube shape made of tubulin subunits, can be broken down and reassembled in centrosome
what do microtubules do
form spindles and hold organelles in place
track for motor proteins
what are microfilaments
thin strands of two chains of actin subunits twisted into helix and they form cell cortex
what is the cell cortex
mesh of micro filaments at cell membrane give animal cells shape
microfilaments are involved in
amoeboid movement
muscle cell contraction
endocytosis/exocytosis
plant cytoplasmic streaming
what are intermediate filaments
medium size
add strength to hair, nails, and dead skin
highly variable used to ID cell types
What are motor proteins
activated by ATP, changes result in motion, each type varies
most common types of motor proteins
myosins, actins, dynins, kinesins
what are kinesins
walk along microtubules dragging cargo
ex; vessicles organelles
what are dynins
walk along microtubules dragging cargo or bending cilia and flagella
what push microtubules past each other
motor proteins
kinesin for mitosis
dynein for cilia motion
what pushes microfilaments past each other
myosin does, to move cell cortex and to contract muscle
endomembrane system
lacks prokaryotes
distinguished trait of all eukaryotes
membranes all physically connected or exchange phospholipids by vesicle formation or assimilation
assimilation
budding off or absorbing vesicles
What parts are in the endomembrane system
Nucleus Endoplasmic reticlum Golgi Vesicles Vacuoles Lysosomes/peroxisomes Cell membrane
What part has the only double layer where both are the same
Nucleus
What three parts have double layers
Nucleus
Chloroplast
Mitochondria
Free ribosomes are located where
Floating in the cytosol
Where are bound ribosomes located
Attached to ER
Who have their own DNA
Chloroplasts
Mitochondria
What is an example of a lysosomes
Peroxisome
What is responsible for modification and finishing f touches
Golgi body
What can proteins have stuck to them
Lipids or sugars
What is an acronym to remember the parts of the endo system
Never Eat Green Vegetables, Vegetables Like Celery
Microtubules acrynom
Tubing- big tubes, hollow in the center, made of tubulin like tubes, you can spin in tubs like spindles, hold you in place like holding organelles in place, and you track down a river in them like tracking down motor proteins. And they can be inflated or deflated like broken down or re assembled
