Endomembrane System Flashcards
(14 cards)
Why are the organelles placed together in endomembrane system?
Because coordination present between these organelles
All the organelles in endomembrane system
Endoplasmic reticulum
Golgi body
Lysosome
Vacuole
Give the sequence in EMS
Endoplasmic reticulum-> Transition Vesicle-> Golgi body-> Mature Vesicle-> Lysosome-> digestion-> Vaccuole
Endoplasmic reticulum is also known as _____
System of membrane
The endoplasmic reticullum divides the cytoplasm in _____ and _____ compartments
Luminal (inside ER)
Extra luminal (outside ER)
Name the components of endoplasmic reticulum
Cisternae
Tubules
Vestibules
Cisternae
Long
Flattened
Granular
Unbranched
Membranous structure
Tubule
Tubular
Branched
Agranular
Irregular (may remain free or associated with cisternae)
Membranous structure
Vesicle
Minute
Sac like
Filled with protein or lipid
Give the two types of endoplasmic reticulum
Rough endoplasmic reticulum
Smooth endoplasmic reticulum
Rough endoplasmic reticulum
Ribosome present
Mainly composed of cisternae (cisternae has ribososmes)
Related to protein synthesis (ribosome produces protein)
Smooth endoplasmic reticulum
Ribosome absent
Mainly composed of tubules (tubules do not have ribosome)
Related to lipids and steroidal hormone synthesis
Functions of endoplasmic reticulum (NCERT)
Synthesis of glycogen
Synthesis of lipoproteins
Synthesis of steroidal hormones
Functions of endoplasmic reticulum
Mechanical support
Intercellular transportation
Lipid synthesis
Lipid synthesis
Protein synthesis
Steroidal hormone synthesis
Formation of nuclear membrane
Formation of golgi body, lysosome and some microbodies
