Cells Flashcards
role of mitochondria
oxidative phosphorylation
ATP synthesis
features of a mitochondrion
contains its own DNA
has a double membrane
what occurs in the outer membrane of a mitochondria
lipid synthesis
fatty acid metabolism
what occurs in the inner membrane of a mitochondria
respiratory chain
production of ATP
what occurs in the matrix of the mitochondria
krebs cycle
what occurs in the intramembranous space of a mitochondria
nucleotide phosphorylation
what occurs at the RER
protein synthesis
- the proteins synthesised by ribosomes are then packaged in the RER for export from the cell
features of the RER
highly folded, flattened membrane sheets
studded with ribosomes
what occurs in the smooth ER
membrane lipid synthesis
and processes synthesised proteins
storage site of calcium ions in skeletal/cardiac muscle
features of the the smooth ER
highly folded flattened membrane sheets
function of golgi apparatus
processes and stores macromolecules synthesised in the ER
modifies and packages proteins from the ER
what does the cis face of the golgi do
receives transport vesicles from the ER and phosphates some proteins
what does the medial golgi do
forms complex oligosaccharides
what does the trans face of the golgi do
proteolysis of peptides into active forms and sort the macromolecules into vesicles
what is the function of vesicles
transport , store and exchange cell membrane between compartments
