cell structure

Question 1

what are the 2 different types of endoplasmic reticulum ad what are the functions of each type?

Answer 1

smooth and rough
smooth is responsible for lipid and steroid synthesis
detoxification of drugs

rough ER is where n linked glycosylation happens

Question 2

what type of cells are rich in RER ?

Answer 2

plasma cells due to antibody secretion
goblet cells due to mucus secretion
pancreatic cells due to insulin secretion

Question 3

what type of cells are rich in smooth ER ?

Answer 3

hepatocytes ( steroid and hormone producing)
p450 in hepatocytes
cells of the adrenal cortex

Question 4

which enzymes is exclusively found in the SER ?

Answer 4

glucose 6 phosphate

Question 4

what is the function of thee golgi app ?

Answer 4

modification of proteins
proteins leave the endoplasmic reticulum too go too the golgi in vesicles

Question 5

what are the 2 systems associated with the golgi apparatus ?

Answer 5

the cis golgi network
trans golgi network

Question 6

what is the difference between the two systems in the golgi app ?

Answer 6

the surface closest to the RER is called the cis face
the other side of the golgi app is called the trans face where proteins exit

Question 7

what are the post translational events that happen in the golgii app ?

Answer 7

addition of n oligosaccharides to asparginine
addition of o oligosaccharides to serine and threonine
mannose 6 phosphate to lysosomal proteins

Question 8

what is an example of a heavily glycosylated product?

Answer 8

mucins
