Production & Secretion of Proteins Flashcards
1
Q
1) What does the nucleus contain and what is the nucleus the site of?
A
it contains the gene / DNA for the protein
it is the site of transcription (DNA to mRNA)
2
Q
2) What translation takes place on the ribosomes and where?
A
protein synthesis translation on the rough endoplasmic reticulum
3
Q
3) Where is the protein transported to?
A
the golgi apparatus in a vesicle
4
Q
4) What modifies the protein?
A
the golgi body
e.g., adds a carbohydrate group - glycoprotein
5
Q
5) What is the protein packed into?
A
a golgi vesicle
6
Q
6) Where is the vesicle transported to?
A
the cell surface membrane
7
Q
7) What is exocytosis?
A
where the vesicle fuses with the membrane e.g. extracellular enzymes
