Question

phospholipids are important molecules in cells. which of statements describe the structure and function of phospholipids. check all that apply they contain a glycerol backbone. the non - polar section attracts water molecules. the phosphate head group is polar. the molecule is an important part of cell membranes. they are a major form of energy storage.

Explanation:

• Phospholipids have a glycerol backbone as part of their structure.
• Their phosphate head is polar (hydrophilic), while the fatty acid tails are non-polar (hydrophobic, repel water).
• They form the lipid bilayer of cell membranes, a key structural component.
• Triglycerides, not phospholipids, are the major energy storage molecules.

Answer:

• They contain a glycerol backbone.
• The phosphate head group is polar.
• The molecule is an important part of cell membranes.
