organelles of the cell UNIT3 Flashcards
(28 cards)
cell’s power house
Mitochondria
Used for energy production
Mitochondria
make 95%of ATP in the cell
Mitochondria
Site of protein synthesis
Ribosomes
Proteins made by free ribosomes usually stay in.
Cytoplasm
Proteins made by fixed ribosomes are usually exported as part of a
membrane
made up of nucleolus
Ribosomes
metabolize lipids
Peroxisome
detoxify chemicals
Peroxisome
make microtubules
Centriole
reduce oxidative stress on cells from free radicals
Peroxisome
help separate chromosomes during mitosis
Microtubules
function:
cell support, movement, division, and transportation in the cell.
Cytoskeleton
contain 3 fibrous proteins: microtubules, intermediate filament, microfilaments
Cytoskeleton
increase absorption area in the cell
Microvilli
longer than cilia & only use by male reproductive cells (sperm) used to propel sperm.
flagellum
have motility to move substances across cell surface, longer than microvilli
Cilia
Support and maintain organelle position
Microtubules
function: cell shape and support
Intermediate filaments
function is movement
Microfilament
comes from the Golgi
Lysosome
contain digestive enzymes for ridding the cell of old organelles or pathogens
Lysosome0
can be used for apoptosis under some conditions
Lysosomes
Programmed cell death/ cell suicide
Apoptosis
