Cell Structure and Function Flashcards
What job do cells have?
make proteins, energy, and make more cells
What organelles are involved in building proteins?
nucleus, ribosomes, rough ER, golgi aparatus, vesicles
Structure of the nucleus
Nuclear envelope that has a double membrane and pores that allow large macromolecules to flow through
Nucleolus function
ribosome production by building ribosome subunits from rNA and proteins
Types of ribosomes are?
Free- in the cytosol and boun-attached to the endoplasmic reticulum
Endoplasmic reticulum function
processes proteins, manufactures membrane, synthesis/hydrolysis of compounds.
Smooth ER function
synthesizes lipids, hydrolysis, membrane production
Rough ER function
produces proteins to exit the cell by packaging them into transport vesicles
Golgi apparatus function
finishes/sorts cell products by putting them into a vesicle
Mitochondria function
produces ATP for the cell to use; has double membrane with highly dolded inner membrane
Vacuoles/vesicles function
move material around the cell and storage
Lysosomes function
digest food, clean/recycle
Centrioles function
help coordinate cell division
Cellular digestion
lysosomes fuse with food vacuoles where polymers are digested into monomers and become nutrients for the cell
What pH do lysosome enzymes work best?
pH level 5
