Question

Plz try to do both if not it’s fine Thank you so much 7. Phospholipids are synthesized A. In mitochondria and released into the cytopl B. On the ER luminal leaflet where they are flipped to d membrane lasm where they are incorporated into membranes stribute them to both the tuminal and eytoplasmic leaflets of the E n the ER cytoplasmic leaflet where they are fipped to distribute them to both the luminal and cytoplasmic leaflets of the ER membrane. flipped to distribute them to both the huminal and D. On the cytoplasmic leaflet of the Golgi apparatus where they are cytoplasmic leaflets of the Golgi membrane E. On the luminal leaflet of the Golgi apparatus where they are lipped to distribute them to both the luminal and eyloplasmic leaflets of the Golgi membrane. 8. In addition to calnexin, there is another chaperone that ensures that proteins are correctly A. Disulfide bonded B. Phosphorylated C. Peptide bonded D. Translated E. Activated

Explanation / Answer

Answer 7. The correct option is C. On the ER cytoplasmic leaflet where they are flipped to distribute them to both luminal and cytoplasmic leaflets of ER membrane.

Phospholipid synthesis occurs in the cytosole adjacent to ER membrane that comprises of proteins like flippase, floppase, GPAT, LPAAT acyl transferases, phosphatase and choline phosphotransferase.

Answer 8. The correct option is A. Disulfide bonded. Calnexin and calreticulin are the chaperons that are specifically involved in the act to retain unfolded or unassembled N-linked glycoproteins in the ER.
