Question

determine whether each statement describes a property of phospholipids, triglycerides, or both. complete the table. phospholipids triglycerides contain a polar phosphate group are energy - storage molecules contain nonpolar fatty acids build cell membranes

Explanation:

1. Phospholipids have a polar phosphate - group due to their structure with a phosphate head. Triglycerides do not have a polar phosphate group.
2. Triglycerides are well - known energy - storage molecules. Phospholipids are not mainly energy - storage molecules.
3. Both phospholipids and triglycerides contain nonpolar fatty acids in their structure.
4. Phospholipids are a major component of cell membranes, forming a bilayer. Triglycerides are not involved in building cell membranes.

Answer:

	phospholipids	triglycerides
