production of proteins

Question 1

what is the pathway of organelles involved in protein production?

Answer 1

• nucleus
• ribosomes
  -rough endoplasmic reticulum
• Golgi apparatus
  -vesicles

Question 2

what’s the role of the nucleus in the production of proteins.

Answer 2

• manufactures the ribosomes
• transcription producing DNA

Question 3

what’s the role of the ribosomes in the production of proteins.

Answer 3

-mRNA attaches to ribosomes after leaving the nucleus
- translation produces a chain of amino acids (polypeptide chain)

Question 4

what’s the role of the rough endoplasmic reticulum in the production of proteins.

Answer 4

• contains lots of ribosomes.
  -folds and processes the polypeptide chain to form a protein

Question 5

what’s the role of the Golgi apparatus in the production of proteins.

Answer 5

modifies proteins and prepares them for secretion

Question 6

what’s the role of the vesicles in the production of proteins.

Answer 6

-transport the proteins to where they need to be.
-vesicles fuse with the cell surface membrane to secrete proteins from the cell by exocytosis.
