Question

Why is it important for peptidoglycan precursors to be sufficiently hydrophobic in order to cross the cell membrane?

A) No materials can cross the membrane without assistance from helper molecules, which are often hydrophobic.

B) The hydrocarbon tails in the phospholipid membrane are hydrophobic, so it is easier for hydrophobic materials to pass through the membrane.

C) Hydrophobic molecules are able to form channels that allow large materials, like peptidoglycan precursors, to pass through the membrane.

D) The phosphate groups in the phospholipid membrane are hydrophobic, so it is easier for hydrophobic materials to pass through the membrane.

B) The hydrocarbon tails in the phospholipid membrane are hydrophobic, so it is easier for hydrophobic materials to pass through the membrane.
