The most likely answer here is 1 and 4.
Answer: D)
Membrane proteins produce phospholids
Explanation:
Membrane proteins in the mitochondria do more than just generate cellular energy. The proteins in the membranes of the mitochondria are complex machines in the nanoworld that mediate the oxygen-coupled generation of energy in cells. Their role in this process is not yet understood in detail.
Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane.
The role of DNA in all cells is to produce molecules of RNA that are involved in protein synthesis. Through the proteins, all the metabolism of the cell is controlled. DNA is also used to synthesize new DNA for daughter cells.
