The diagram below shows a phospholipid molecule.



Which of the following best describes how this molecule is produced by eukaryotic cells?

Question 12 options:

The nucleus sends out mRNA to the smooth ER (endoplasmic reticulum) so it can assemble the phospholipids using amino acids that are transported into the cell by the cell membrane. Vacuoles carry glucose to the smooth ER to supply the energy.


The enzymes needed to assemble it are from the Golgi. The smooth ER (endoplasmic reticulum) assembles the phospholipids using fatty acid tails that are transported into the cell through the cell membrane. Energy for the reaction comes from the mitochondria as ATP.


The enzymes needed to assemble it are from ribosomes. The rough ER (endoplasmic reticulum) assembles the phospholipids using energy from the mitochondria. The cell membrane transports new amino acids into the cell that are changed in the phospholipid.


The nucleus sends instructions out to the smooth ER (endoplasmic reticulum) to build the phospholipid. The cell membrane transports fatty acid tails into the cell to be used, and energy for the reaction comes from the mitochondria as ATP.
