Endomembrane System

Question 1

Endomembrane System

Answer 1

• essentially the transportation + product processing section of the cell
• compartmentalizes cell
• components: nuclear envelope, ER, GA, vesicles

Question 2

Secretion

Answer 2

Process that allows products made by the cell to leave

Question 3

Step 1

Answer 3

DNA used as template to transcribe into mRNA

Question 4

Step 2

Answer 4

mRNA leaves nucleus through nuclear pores & enters RER

Question 5

Step 3

Answer 5

Ribosome (rRNA + protein in 2 subunits) reads mRNA strand & work w/tRNA to create a polypeptide chain

Question 6

Step 4

Answer 6

Completed polypeptide chain passes into RER where it is modified into a secondary structure

Question 7

Step 5

Answer 7

Packaged into transport vesicle & shipped to GA

Question 8

Step 6

Answer 8

Transport vesicle merges w/GA & polypeptide chain is further modified as it moves through the inner & outer faces
-protein is completed

Question 9

Step 7

Answer 9

Packaged into secretory vesicle & shipped to plasma membrane

Question 10

Step 8

Answer 10

Secretory vesicle merges w/plasma membrane & releases contents
-type of exotysis called secretion
