cell organelle Flashcards
Ribosomes are made of what?
Two subunits made of Ribosomal RnA and Protein
What is ribosome’s function?
Synthesize proteins according to the mRNA sequence
Ribosomes are found in?
all forms of life, reflecting the common ancestry of all known life.
Endoplasmic reticulum occurs in?
2 forms smooth and rough
Endoplasmic reticulum function
provides mechanical support, carries out protein synthesis on membrane-bound ribosomes, and plays a role in intracellular transport.
Rough ER is associated with
membrane-bound ribosomes
Rough er function
aids in synthesis of proteins on bound
ribosomes; adds carbohydrates to proteins to make glycoproteins; distributes transport vesicles produces new membrane
Smooth ER function
detoxification and lipid synthesis.
Golgi complex structure
membrane-bound structure that consists of a series of flattened membrane sacs.
Functions of the Golgi
Modifies products of the ER
Manufactures/ synthesizes certain macromolecules
Sorts and packages materials into transport vesicles
Mitochondria structure
double membrane.
Mitochondrial double membrane provides?
compartments for different metabolic reactions.
Mitochondria outer membrane is
smooth
Mitochondria Inner membrane has
infoldings folded into cristae-foldings of inner membrane increases surface area for more electron transport and atp sythesis to occur here
Mitochondria function
sites of cellular respiration, that uses oxygen to
generate ATP
Lysosomes structure
are membrane-enclosed sacs that contain hydrolytic enzymes
Lysosomes function
Breakdown of ingested substances,
cell macromolecules, and damaged
organelles for recycling
Vacuole structure
Large membrane-bounded vesicle
Vacuole function
Vacuoles have many roles, including storage
and release of macromolecules and cellular
waste products. In plants, it aids in water balance for plants
Chloroplasts are found in?
Photosynthetic algae and plants
Chloroplasts structure
DOUBLE outer membrane around fluid stroma which contains thylakoids stacked into grana
Thylakoids
organized in stacks called grana, light dependent reactions of photosynthesis occur here
stroma
fluid within the inner chloroplast membrane and outside of the thylakoid.
Chloroplast function
Photosynthesis
