Synthesis of membrane components Flashcards
1
Q
Where are lipids and proteins synthesised?
A
In the endoplasmic reticulum.
2
Q
Which side are lipids synthesised on the ER?
A
Smooth and inserted into the membrane.
3
Q
Where does the synthesis of all proteins begin?
A
Cytosolic ribosomes.
4
Q
Where does the completion of cytosolic proteins occur?
A
In cytosolic ribosomes and proteins remain there.
5
Q
What do transmembrane proteins carry?
A
A signal sequence
6
Q
What does the transmembrane’s signal sequence do?
A
Halts translation and directs the ribosome synthesising the protein to dock with the ER, forming RER
7
Q
What happens after docking?
A
Translation continues and the protein is inserted into the membrane of the endoplasmic reticulum.
