Most important and abundant one are the phospholipids - amphiphatic molecules with an hydrophilic head and a hydrophobic hydrocarbon tails. They compose the membrane bilayer. Also important are the membrane proteins, which can be periheric and internal and can serve as channels, receptors, pumps etc.
Depending on the cell type the membrane can also contain cholesterol (in animal cells, enhances the membrane stability) or hopanes(in prokaryotes, same function as cholesterol) or ether-phospholipids with branched hydroharbon tails(in archaea, make the membranes more stable and resistant to severe conditions, as archaeas are extremophiles)
Answer:

Answer:
They would be the enzymes that assimilate the presence of Q to generate a metabolism that encourages growth.
And also those that are X-forming, which is what is always present in cells.
Explanation:
Therefore, all the enzymes that assimilate the amino acid Q continue to function.
In simple words, in this situation, amino acid Q went from being a non-essential amino acid (because it was manufactured in-house) to being an essential amino acid (which, if or if, must be administered by the medium due to lack of own production in order to generate growth) .
C
Explanation:
Molecule C would be least soluble in water because it is not a polar compound/molecule. It also lacks any unit that can combine with water to form a good hydrogen bond.
- The general rule of solubility is that like dissolves likes.
- Polar molecules will only dissolve in polar solvent.
- Water is a polar solvent with hydrogen bonds in them.
- Hydrocarbons typically have weak london dispersion forces between them and they are not polar.
- Other compounds have functional groups that can form hydrogen bond with water.
