Lecture 2c - 2e Flashcards
Describe the Golgi apparatus (3)
Modifies products in the ER
Manufactures certain macromolecules
Sorts and packages materials into transport vesicles
Is the cis or trans face of the ER facing the nucleus ?
the cis face - the trans face faces the surface
what is autophagy?
Eating themselves and eating things from its internal cellular contents. Recycling of cellular components
Explain Phagocytosis
Cells eating and digesting potential harmful bacteria with the help of fusion with lysosomes
What are vesicles used for
to organize cellular processes - specific cells to organize different processes
How do vesicles form?
Naturally through the process of exocytosis, endocytosis, and transport of materials within the plasma membrane
Do cilia and flagella move the same
no they don’t
are mitochondria and chloroplasts a part of the endomembrane system
no
What happens in mitochondria?
site of cellular respiration
What are peroxisomes
oxidative organelles - bigger molecules become very small in oxidation processes that happen in the peroxisomes
how many membranes do mitochondria have ?
2 - smooth inner and outer membrane
Where does the ATP production happen in mitochondria?
Inner membrane
what is stroma?
the liquid in between thylakoids and inside the inner membrane of the CHLOROPLASTS
What does the cytoskeleton do
anchors organelles and internal structures
it is a network of fibres
Cytoskeleton is composed of 3 types of molecular structures, what are they? What is their order of thickness?
Microtubules - thickest
Microfilaments - thinest
Intermediate filaments - diameters in middle range
