A phospholipid is a biomolecule composed of a phosphate group that is bonded to two lipid chains. Which of the following correctly describes the nature of those two components? (a) The phosphate group is hydrophobic, and the lipid chains are hydrophilic. (b) Both the phosphate group and the lipid chains are hydrophilic. (c) Both the phosphate group and the lipid chains are hydrophobic. (d) The phosphate group is hydrophilic, and the lipid chains are hydrophobic.
A phospholipid __________. a. has both polar and nonpolar regions b. is made up of a triglyceride bonded to a phosphate group c. is a building block of ATP d. can donate both cations and anions in solution
