Question

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

Explanation:

1. are energy - storage molecules: Triglycerides are well - known for long - term energy storage. Phospholipids are mainly for cell membranes but can also store some energy. So both can be energy - storage molecules.
2. contain a polar phosphate group: Phospholipids have a polar phosphate head, while triglycerides are made of glycerol and fatty acids and do not have a phosphate group. So only phospholipids have this.
3. build cell membranes: The cell membrane is mainly composed of a phospholipid bilayer. Triglycerides are not part of the cell membrane structure. So only phospholipids do this.
4. contain nonpolar fatty acids: Phospholipids have two nonpolar fatty acid tails, and triglycerides have three fatty acid chains which are nonpolar. So both contain nonpolar fatty acids.

Answer:

	phospholipids	triglycerides
contain a polar phosphate group	✔️	❌
build cell membranes	✔️	❌
contain nonpolar fatty acids	✔️	✔️
